[PATCH] libosmo-sccp[master]: sccp: ensure addressbook entry names are unique

sccp: ensure addressbook entry names are unique

It is possible to add two (or more) different
sccp-addresses under the same name, when the
addresses are defined in different cs7 instances.

Add a check to make sure an address name is not
used multiple times
