qcacld-3.0: Reject all vdev commands for TDLS in roaming

All the vdev and peer related commands are forbidden, when the
roaming happens in the system.
Firmware roaming module does vdev_stop, once the roaming is
successfully completed. Part of vdev stop, firmware will delete
all TDLS peers. So after roaming is completed, as part of
roam_sync_complete, host should not send peer_delete. If host
sends peer_delete then FW will not be able to send
peer_delete_resp_event as peer is already deleted
during roaming.

Make changes to reject all vdev and management commands
to firmware, when roaming is in progress in the system.
