[PATCH] libosmocore[master]: GPRS: check and report local address used for NSE

[Max]

Review at  https://gerrit.osmocom.org/4395

GPRS: check and report local address used for NSE

When dumping NSE via vty:
* check which local address would be used to communicate with a given
  NSE and print it
* print link layer type last to make output more consistent
