xfs: check for cow blocks before trying to clear them
There's no point in allocating a transaction and locking the inode in preparation to clear cow blocks if there actually are any cow fork extents. Therefore, move the xfs_reflink_cancel_cow_range hunk to xfs_inactive and check the cow ifp first. This makes inode reclamation run faster. Signed-off-by: Darrick J.
