xfs: avoid shared rmap operations for attr fork extents
During code review, I noticed that the rmap code uses the (slower) shared mappings rmap functions for any extent of a reflinked file, even if those extents are for the attr fork, which doesn't support sharing. We can speed up rmap a tiny bit by optimizing out this case. Signed-off-by: Darrick J.
