    kgssapi: Remove broken MOD_UNLOAD code
    
    The module panicked at unload with "recursing but non-recursive rw".
    There is a comment that "Unloading of the kgssapi module is not
    currently supported" and the MOD_UNLOAD case falls through to returning
    EOPNOTSUPP anyway.  Just #if 0 the code in the unload path, leaving it
    as a hint in case someone implements unload support later on.
