LLC: Don't dispatch XID frames into GMM

For some odd reasons the XID is not a separate SAPI but has been kludged into
the GMM SAPI.  This means we ahve to be careful not to dispatch XID frames into
GMM.  We do this by introducing an explicit check for UI frames before the
dispatch to GMM.

The previous code already was doing "the right thing" but printed occasional
messages like "gprs_gmm.c:2082 Unknown GSM 04.08 discriminator 0x01: 01 00 0e
00 32 11 03 16 01 90 63 28 0b".  Those should be gone after this patch.
