bsc_nat_fsm: tweak get_peer_addr
Rename the function from sccp_sap_get_peer_addr_in to get_peer_addr to make the code using it slightly more readable. The _in at the end of the function is not needed anymore, this was used to differentiate from peer_addr_out which was used in the caller code before the connection mapping was implemented in I1556aa665fbb0a97507f98794e74820731fa6935. Now instead of peer_addr_out, conn->bsc->addr or conn->msc->addr are used.
Rename variable arguments to sccp_inst and addr to be consistent with the variable names in the callers.
