qcacmn: Handle EV_DISCONNECT_ACTIVE event in roaming state

In the case of Roam Start sub-state, if a new connect/disconnect
is received, an internal disconnect/actual disconnect is queued
in serialization and then the state is changed to connecting
or disconnecting, but if the disconnect command becomes active
directly the EV_DISCONNECT_ACTIVE is received in roam substates
but is not handled.

As EV_DISCONNECT_ACTIVE is not handled the disconnect is not
processed and VDEV can remain in UP state while CM assuming that
the disconnect is completed will allow a new connection which
cause 2nd BSS peer creation.

Fix is to handle EV_DISCONNECT_ACTIVE event in Roam sub-states.
