btrfs: return errors from unpin_extent_range()
Handle the lookup failure of the block group to unpin, this is a logic
error as the block group must exist at this point. If not, something else
must have freed it, like clean_pinned_extents() would do without locking
the unused_bg_unpin_mutex.
Push the errors to the callers, proper handling will be done in followup
patches.
