    xfs: check magic numbers in dir3 leaf verifier first
    
    Calling xfs_dir3_leaf_hdr_from_disk() in a verifier before
    validating the magic numbers in the buffer results in ASSERT
    failures due to mismatching magic numbers when a corruption occurs.
    Seeing as the verifier is supposed to catch the corruption and pass
    it back to the caller, having the verifier assert fail on error
    defeats the purpose of detecting the errors in the first place.
    
    Check the magic numbers direct from the buffer before decoding the
    header.

    xfs: fix some minor sparse warnings
    
    A couple of simple locking annotations and 0 vs NULL warnings.
    Nothing that changes any code behaviour, just removes build noise.

    xfs: fix endian warning in xlog_recover_get_buf_lsn()
    
    sparse reports:
    
    fs/xfs/xfs_log_recover.c:2017:24: sparse: cast to restricted __be64
    
    Because I used the wrong structure for the on-disk superblock cast
    in 50d5c8d ("xfs: check LSN ordering for v5 superblocks during
    recovery"). Fix it.
