qcacld-3.0: Unregister wext interface, on STA interface down

Explorar el Código 
Host registers wext handlers, during STA interface UP. But not
unregistering during interface down, lending user to issue iwpriv
commands though interface is down.

Unregister wext interface, by initializing wireless_handlers to NULL
during interface down.
