bcachefs: Recovery no longer holds state_lock
state_lock guards against devices coming or leaving, changing state, or
the filesystem changing between ro <-> rw.
But it's not necessary for running recovery passes, and holding it
blocks asynchronous events that would cause us to go RO or kick out
devices.
