gsm_pchan2chan_nr: Fix conversion of CCCH_LCHAN
Previous implementation made no sense, since chan_nr is never read
before being set below from lchan_nr.
Furthemore, if lcahn_nr=CCH_LCHAN=4, then:
cbits = 0x4 + lchan_nr = 0x8 = b1000 which then becomes SDCCH8 according
to GSM 08.58 9.3.1, so it's totally wrong:
SDCCH/8 + ACCH 0 1 T T T
