bsc_msc_ip: Crash fix on MO-Call starting with a SDCCH
We do not assing a GSM Subscriber to Mobile Originated calls, when
requesting a SDCCH and then starting call control we will crash here
due trying to copy a NULL subscriber from the lchan to the other.
We do not need to know the IMSI at the BSC so it is okay to not
copy the subscriber around, we could even kill all subscriber handling
in the future.
