Vadim Yanitskiy cce691d19e rlcmac: do not attempt to decode PTCCH/D blocks, discard them 
PTCCH/D blocks use different encoding than PDTCH/D blocks, and passing
them to gprs_rlcmac_handle_gprs_dl_block() results in decoding errors:

  DRLCMAC NOTICE rlcmac.c:496 Failed decoding dl ctrl block:
  7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 7f 2b 2b 2b 2b 2b 2b 2b

We don't implement PTCCH yet, so discard these blocks starting at
Fn=12 within the period of 104 frames (see 3GPP 45.002, table 6).
