xfs: check the flags earlier in xfs_attr_match

Source kernel commit: f49af061f49c004fb6df7f791f39f9ed370f767b

Checking the flags match is much cheaper than a memcmp, so do it early
on in xfs_attr_match, and also add a little helper to calculate the
match mask right under the comment explaining the logic for it.
