sms_next_rp_msg_ref(): use direct pointer to next_rp_ref counter
libbsc and libmsc will have separate subscriber connection structs. Hence don't rely on gsm_subscriber_connection, but work on a direct pointer to the counter for the next RP reference. The only very thin function in gsm_04_11_helper.c thus becomes obsolete: drop the entire file. Change-Id: I2a2e9ba6a981a385d1f8f07acbe03536ffed0072
