Btrfs: skip merge part for delayed data refs
When we have data deduplication on, we'll hang on the merge part
because it needs to verify every queued delayed data refs related to
this disk offset but we may have millions refs.
And in the case of delayed data refs, we don't usually have too much
data refs to merge.
So it's safe to shut it down for data refs.
