xfs: don't catch dax+reflink inodes as corruption in verifier
We don't yet support dax on reflinked files, but that is in the works.
Further, having the flag set does not automatically mean that the inode
is actually "in the CPU direct access state," which depends on several
other conditions in addition to the flag being set.
As such, we should not catch this as corruption in the verifier - simply
not actually enabling S_DAX on reflinked files is enough for now.
Fixes: 4f435ebe7d04 ("xfs: don't mix reflink and DAX mode for now")
