xfs: inode recovery does not validate the recovered inode

commit 038ca189c0d2c1570b4d922f25b524007c85cf94 upstream.

Discovered when trying to track down a weird recovery corruption
issue that wasn't detected at recovery time.

The specific corruption was a zero extent count field when big
extent counts are in use, and it turns out the dinode verifier
doesn't detect that specific corruption case, either. So fix it too.
