Change subject: use RUA procedure code for rua_to_scu() arg ......................................................................
use RUA procedure code for rua_to_scu() arg
Instead of osmo_scu_prim_type, use RUA_ProcedureCode to tell rua_to_scu() the RUA message type being handled.
Cosmetically prepare for upcoming patch that completely moves osmo_scu_prim composition from rua_to_scu() to a new context map SCCP FSM.
