    xfs: modify verifiers to differentiate CRC from other errors

    Modify all read & write verifiers to differentiate
    between CRC errors and other inconsistencies.

    This sets the appropriate error number on bp->b_error,
    and then calls xfs_verifier_error() if something went
    wrong.  That function will issue the appropriate message
    to the user.

    xfs: print useful caller information in xfs_error_report

    xfs_error_report used to just print the hex address of the caller;
    %pF will give us something more human-readable.

    xfs: add xfs_verifier_error()

    We want to distinguish between corruption, CRC errors,
    etc.  In addition, the full stack trace on verifier errors
    seems less than helpful; it looks more like an oops than
    corruption.

    Create a new function to specifically alert the user to
    verifier errors, which can differentiate between
    EFSCORRUPTED and CRC mismatches.  It doesn't dump stack
    unless the xfs error level is turned up high.

    Define a new error message (EFSBADCRC) to clearly identify
    CRC errors.  (Defined to EBADMSG, bad message)

    xfs: add helper for updating checksums on xfs_bufs

    Many/most callers of xfs_update_cksum() pass bp->b_addr and
    BBTOB(bp->b_length) as the first 2 args.  Add a helper
    which can just accept the bp and the crc offset, and work
    it out on its own, for brevity.

    xfs: Use defines for CRC offsets in all cases

    Some calls to crc functions used useful #defines,
    others used awkward offsetof() constructs.

    Switch them all to #define to make things a bit cleaner.

    xfs: skip pointless CRC updates after verifier failures

    Most write verifiers don't update CRCs after the verifier
    has failed and the buffer has been marked in error.  These
    two didn't, but should.

    Add returns to the verifier failure block, since the buffer
    won't be written anyway.
