qcacld-3.0: clean flag chan_switch_in_progress if link tear down

If the channel-list that AP is asking us to switch is invalid, then
we cannot switch the channel. Just call lim_tear_down_link_with_ap()
to disassociate from AP. We will find better AP.
So, vdev_stop, peer_del, vdev_down will be sent. VDEV_MLME state
is back to init.

But, we didn't clean flag chan_switch_in_progress. When better AP
found, vdev will start. Because flag chan_switch_in_progress is true,
WMI_VDEV_RESTART_REQUEST_CMDID sent. But WMI_VDEV_START_REQUEST_CMDID
is expected. And then WMI_VDEV_RESTART_RESP_EVENT received.

Host will send WMI_PEER_SET_PARAM_CMDID with parameter ID
WMI_PEER_CHWIDTH(4) once WMI_VDEV_RESTART_RESP_EVENT received.
However, FW was already back to INIT state because vdev already down.
PEER state was init state, PEE_CHWIDTH set not allowed.

So, flag chan_switch_in_progress should be clean if vdev_stop sent.
