    bsc_scan_msc_msg: check protocol discriminator
    
    The function assumed an MM protocol discriminator without verifying it.

    GSM 04.08: apply bitmask functions, fix bitmask use
    
    Replace hardcoded protocol discriminator and message type bitmasks with
    function calls recently introduced in libosmocore.
    
    Note that the release 98 bitmasks slightly differ from the release 99 bitmasks.
    This patch uses the "default" gsm48_hdr_msg_type invocation, thus it depends on
    libosmocore whether 98 or 99 bitmasks are used.
    
    In some places, use of the bitmask was erratic. Fix these implicitly by
    employing the bitmask functions:
    
     * bsc_msg_filter.c: bsc_msg_filter_initial(): RR vs. MM messages.
     * osmo_bsc_filter.c: bsc_find_msc() and bsc_scan_bts_msg(): RR vs. MM
       messages.
     * bsc_nat_rewrite.c: bsc_nat_rewrite_msg(): SMS vs. CC messages.
     * bsc_ussd.c: no bitmask is applicable for the message types used here.

    Remove unused auth code and add comment
    
    As commented in the code, the GSM_SECURITY_AUTH_FAILED path is never invoked by
    the gsm48_secure_channel() function as it is today.
    
    Note that the upcoming Iu auth will probably add a GSM_SECURITY_AUTH_FAILED
    status. In that case, sending a LU Reject immediately may be desirable, but
    arguably a bit of timeout could make life harder for auth attackers.
    
    The code removed by this patch doesn't send out a LU Reject ever, since a call
    to release_loc_updating_req() only releases the connection. To reject, a call
    to gsm0408_loc_upd_rej() would be necessary, as seen in loc_upd_rej_cb().
    
    And finally, if _gsm0408_authorize_sec_cb() doesn't do anything about anything,
    the same loc_upd_rej_cb() will be run by a timeout and send a LU Reject
    properly (as commented in the code).
