From: Darrick J. Wong <darrick.wong@xxxxxxxxxx>
Convert the last of the open coded corruption check and report idioms to
use the XFS_CORRUPT_ON macro. In a subsequent patch we are going to add
health reporting to the code block under each corruption check, so we
don't bother to clean out "{ return -EFSCORRUPTED; }".
