This patch checks the SRES value in response against the value stored in mm->auth_triplet.sres. If they don't match, an Auth & Ciph Reject message is sent to the MS. If they match, the mm->is_authenticated flag is set. Note that the procedure will not be started yet.

It also makes it more difficult to restart the procedure after timeout, which is not implemented yet. In addition, the timer is not properly stopped when an AUTH & CIPH response is received. This patch removes this timer start from gsm48_tx_gmm_auth_ciph_req, adds the retransmission of Auth & Ciph requests to the timer callback function, and properly stops the timer in gsm48_rx_gmm_auth_ciph_resp.

In addition, gsm48_tx_gmm_auth_ciph_req uses a wrong encoding (two byte TV instead of two nibbles TV) of the CKSN information element. This patch fixes the encoding of the CKSN IE and enables the functions mentioned above.
