[GPRS] NS: Always start NS-ALIVE procedure after RESET
So far, we only started the ALIVE procedure on RESET-ACK if the
remote end was the SGSN. This resulted in the BSS->Proxy connections
only being tested for alive-status from the BSS side, but not from
our side.
Also: export nsvc_by_nsvci() function as a public API function.
