Kernel configures mc address list once association/NDP connection
happens. Host driver flushes the existing list whenever a new list
is received from kernel. Also, it's expected to cleanup the final
list as part of disconnection/NDI cleanup.
Currently, host expects the vdev/NDI state to be ASSOCIATED
in-order to flush the final configured list. But the STA vdev/NDI
state is already moved to DISCONNECTED by the time host tries to
flush the list from firmware. So, host doesn't send flush command
to firmware and it just flushes internal list from driver adapter.
This results in leaving the final configured entries uncleaned
in firmware and the mc list exhausts in few such iterations as the
firmware supports limited size(32).
Don't check for vdev/NDI state and always issue flush command to
firmware as part of disconnect to avoid this.
