bcachefs: bch2_extent_ptr_desired_durability()
This adds a new helper for getting a pointer's durability irrespective
of the device state, and uses it in the the data update path.
This fixes a bug where we do a data update but request 0 replicas to be
allocated, because the replica being rewritten is on a device marked as
failed.
