wifi: cfg80211: restore netns_immutable on failures

Browse source

Switching a wiphy's netns has to clear netns_immutable before moving
interfaces, but then if any of the interfaces fails to move, it gets
netns_immutable cleared forever. Then userspace can move it by itself,
breaking the assumption that they all move together.

Fix the order here and always reset netns_immutable after attempting
the move.
