Liu Bo f5749e3720 Btrfs: do not run snapshot-aware defragment on error ...

commit 6f519564d7 upstream.

If something wrong happens in write endio, running snapshot-aware defragment
can end up with undefined results, maybe a crash, so we should avoid it.

In order to share similar code, this also adds a helper to free the struct for
snapshot-aware defrag.
