gprs: fix has_valid_nsvc(): permit local udp port 0

NSVC local port 0 is actually a valid value, which tells the PCU to
pick a random port for bind()ing.  It was supported before 315af2f9e,
but now osmo-bsc would simply ignore NSVCs with 'local udp port 0'
and leave the respective MOs unconfigured in the BTS.

Fixes: 315af2f9e "bts: ipa/osmo-bts/sysmobts: MO: add support for the second NSVC"
