gbproxy: Refuse to configure conflicting NSEIs

Currently it is possible to set the secondary SGSN NSEI to the same
value like the (primary) SGSN NSEI. This leads to undefined behaviour
and is hard to recognize.

This patch adds checks to either NSEI configuration command to refuse
conflicting values.
