btrfs: reduce block group critical section in btrfs_free_reserved_bytes()
[ Upstream commit 8b6fa164ab59f9e3f24e627fe09a0234783e7a8b ]
There's no need to update the space_info fields (bytes_reserved,
max_extent_size, bytes_readonly, bytes_zone_unusable) while holding the
block group's spinlock. So move those updates to happen after we unlock
the block group (and while holding the space_info locked of course), so
that all we do under the block group's critical section is to update the
block group itself.
