[PATCH] Btrfs: fix a deadlock on chunk mutex
An user reported that he has hit an annoying deadlock while playing with
ceph based on btrfs.
Current updating device tree requires space from METADATA chunk,
so we -may- need to do a recursive chunk allocation when adding/updating
dev extent, that is where the deadlock comes from.
If we use SYSTEM metadata to update device tree, we can avoid the recursive
stuff.
