From: Josef Bacik <josef@xxxxxxxxxxxxxx>
commit 34d1eb0e599875064955a74712f08ff14c8e3d5f upstream.
If we fail to update a block group item in the loop we'll break, however
we'll do btrfs_run_delayed_refs and lose our error value in ret, and
thus not clean up properly. Fix this by only running the delayed refs
if there was no failure.
