Host driver moves VDEV SM to IDLE_DUE_TO_LINK_SWITCH any link
switch failure to handle events such as DISCONNECT_REQ which
gets dropped if the VDEV is in INIT state.
Disconnect request on any ML VDEV initiates disconnect on partner
VDEVs as well if they are either in connected or connecting state
but not if in IDLE_DUE_TO_LINK_SWITCH state. This leaves the VDEV
in this new IDLE_DUE_TO_LINK_SWITCH state instead of in INIT state.
Include VDEVs which are in IDLE_DUE_TO_LINK_SWITCH during partner
VDEV disconnect so that VDEV SM moves to INIT.

Issue happens during following scenario:
1. Connecting to ML AP1 (with SSID1) and disconnect.
2. Connecting to ML AP2 (with SSID2), as part of that vdev
is destroyed and created but stored keys for AP1 are not reset.
3. Disconnect for ML AP2.
4. Connect to ML AP1.
Now host driver sends stored keys FW instead of the newly
generated keys sent by supplicant.
To fix this during ML dev initialization
clear the stored keys.

Currently host is directly acting on the link_id for which link switch
is requested, if the link is already active on the other vdev if the
link switch is not sanitized resulting in firmware ending up
in bad state.
Reject the link switch if the link is already active on different vdev.

If connection fails, CM state will be moved to INIT state and
kernel will not be made aware of this connection failure in case
of link switch and treats the interface as if it is connected.
In such case kernel and host will be out of sync and because of
this if any disconnect request is received host will drop them
immediately as VDEV is in INIT state.
Introduce new substate of VDEV for INIT state. If VDEV moves to
INIT state either due to link switch disconnect or link switch
connect failure, instead of being in INIT-IDLE state move VDEV
to INIT-IDLE_DUE_TO_LINK_SWITCH. If any disconnect request is
received in INIT-IDLE_DUE_TO_LINK_SWITCH state then instead of
dropping the request forcefully queue the disconnect and proceed
for disconnect to notify kernel.
Drop link switch connect will be dropped if VDEV is not in
INIT-IDLE_DUE_TO_LINK_SWITCH state.

Currently, in some API such as
"wlan_cfg80211_tdls_add_peer_mlo", when driver gets vdev, it is
MLO vdev, so it uses WLAN_MLO_MGR_ID ID, but when it tries to put
the vdev, since disconnection happens and mlo flag is cleared,
so it uses WLAN_OSIF_TDLS_ID ID which is non-ML vdev.
This causes release of vdev reference from different id for which
it never takes reference and result in crash.
To fix this, use same debug id throughout function. For that,
generalize the get_ml_vdev API by passing the debug id as
argument to the function.

In response to host set link request, FW might send link switch
request where FW will wait for response of link switch in order
to send response of set link. As set link is already in
serialization link switch will be in pending queue.
This will lead to dead lock case where set link in serialization
is waiting for FW response where FW is waiting for link switch
response which is in pending queue due to set link command.
To avoid this dead-lock, do not serialize link switch request
due to set link as FW will send the reason code as HOST_FORCE.
