GPRS_Components: use imsi record member
The function f_pcuif_rx_pch_pag_req1 tries to read the IMSI suffix from
the raw data that was exchanged on the PCUIF interface. This is no
longer the appropriate way in PCUIF v.11. There is now a dedicated imsi
member in type record BTS_CCCH_Block, which is used for that purpose.
