From: Filipe David Borba Manana <fdmanana@xxxxxxxxx>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit e84cc14213e2c81ae5a2da341a9da0d58a1dbfad upstream.
In extent-tree.c:btrfs_write_dirty_block_groups(), if the call to
write_one_cache_group() failed, we would return without putting
the block group first.
