b43: avoid unregistering device objects during suspend
Modify the b43 driver to avoid deadlocking suspend and resume, which happens
as a result of attempting to unregister device objects locked by the PM core
during suspend/resume cycles. Also, make it use a suspend-safe method of
unregistering device object in the resume error path.
