xfs: properly handle free inodes in extent hint validators

Source kernel commit: d4a34e16555708bab5b67e679a95f055d8ef9882

When inodes are freed in xfs_ifree(), di_flags is cleared (so extent size
hints are removed) but the actual extent size fields are left intact.
This causes the extent hint validators to fail on freed inodes which once
had extent size hints.

This can be observed (for example) by running xfs/229 twice on a
non-crc xfs filesystem, or presumably on V5 with ikeep.

Fixes: 7d71a67 ("xfs: verify extent size hint is valid in inode verifier")
Fixes: 02a0fda ("xfs: verify COW extent size hint is valid in inode verifier")
