    Eliminate unnecessary UFS1 integrity checks.
    
    The UFS1 integrity checks added in FreeBSD 14 were too aggressive
    for UFS1 filesystems created in FreeBSD 4 and 9 systems. This patch
    removes those tests which can be done safely since they are not
    relevant to the current implementation of UFS1.
    
    This is a follow-on report to bug report 264450 (comments 21-28).
