gprs: Fix bssgp_rcvmsg to handle signalling msgs with BVCI IE

Currently BSSGP messages with an NS BVCI of 0 (signalling) are
discarded if they aren't RESET messages. Thus valid signalling
messages (e.g. BLOCK) are not handled properly, because the BVCI IE
is ignored if it present. Instead a STATUS message referring to BVCI
0 (instead of the BVCI used in the BLOCK message) is returned.

This patch changes the implementation to use the BVCI contained in
the BVCI IE if that is present in a signalling message.

It fixes BSSGP BLOCK/UNBLOCK for the osmo-sgsn.

Note that signalling messages without an BVCI IE (e.g.
SUSPEND/RESUME) are still rejected.
