gprs_ns2: sns: remove the initial SNS NSVC if it's not part
A SNS configuration can be done over a NSVC, however this initial NSVC doesn't
need to be part of the configuration.
Those NSVC need to be removed when the configuration is done.
This wrong behaviour can be seen in the vty `show ns` on

The UNCONFIGURED NSVC should not be present in when SNS is in CONFIGURED.
