qcacmn: clean up inactive peers/vdevs during driver unload

DP references of the peer will be removed once we receive PEER
unmap message from the firmware. If the firmware has failed to
send the peer unmap message (due to an assert in FW), then the
peer entries will remain the inactive peer list and will trigger
a explicit QDF_BUG() during driver unload.

Force clean the inactive peer/vdev list during driver unload in such
cases.
