    namei: Set inconsistent linktable linkCount to 0
    
    Currently, if we detect an inconsistent linktable filename (where the
    filename indicates it's for a different volume than the directory path
    indicates), we don't set the linkCount for the inode info. This means
    that our caller will get random garbage for the linkCount.
    
    In many cases this value is ignored, but for the salvager, if this is
    the only linktable file we find, we treat it as the linktable we
    should be using. Thus, if linkCount contains undefined data, we might
    try to INC or DEC the linktable a bunch of times, depending on what
    random stack garbage the linkCount is filled with.
    
    The salvager shouldn't be INC/DEC'ing these linktables according to
    the their linkCount anyway, but in the meantime, at least ensure that
    this doesn't contain stack garbage, so we ensure that we won't try to
    INC or DEC this thousands or millions of times.
