Change subject: gsm_04_08_rr: silently ignore RR UTRAN Classmark Change

gsm_04_08_rr: silently ignore RR UTRAN Classmark Change

Some UMTS capable phones (such as SE K800i) send this message
together with the 'normal' RR Classmark Change, what makes
osmo-bsc log the following warning:

  DCHAN NOTICE gsm_04_08_rr.c:1037
      (type=SDCCH) Unknown RR message: UTRAN Classmark Change

We don't handle it, so just ignore without logging anything.
