libosmo-mgcp: Connection Identifiers are allocated by MGW, not CA

The MGCP connection identifier is allocated by the MGW while processing
the CRCX, see RFC3435 2.1.3.2:. Including/Accepting a connection
identifier in CRCX is "forbidden" as per RFC3435 Section 3.2.2.

So the MGW side must *reject* a CRCX message with 'I' parameter, and
allocate a connection identifier which is subsequently returned in the
response.

Closes: OS#2648
