xfs: enable CoW for realtime data
Update our write paths to support copy on write on the rt volume. This
works in more or less the same way as it does on the data device, with
the major exception that we never do delalloc on the rt volume.
Because we consider unwritten CoW fork staging extents to be incore
quota reservation, we update xfs_quota_reserve_blkres to support this
case. Though xfs doesn't allow rt and quota together, the change is
trivial and we shouldn't leave a logic bomb here.
While we're at it, add a missing xfs_mod_delalloc call when we remove
delalloc block reservation from the inode. This is largely irrelvant
since realtime files do not use delalloc, but we want to avoid leaving
logic bombs.
