msc: f_call_hangup: add missing rx MNCC_REL_cnf
Add the missing rx of MNCC_REL_cnf to f_call_hangup for the MO case
(called with release_by_ms = false, see f_mo_call()).
This is in preparation for running f_mo_call several times in a row to
test multiple bearer services in a CSD test (follow up patch). Without
this patch, calling f_mo_call_establish() for the second time fails to
rx the MNCC_RTP_CREATE because the REL cnf is still in the port. This
leads to a timeout of X2 and OsmoMSC sending a CC RELEASE.
Adjust the log numbers next to f_call_hangup to re-use numbers 2 and 3
from above, as only one of the two code paths gets executed (similar to
numbers 5 and 6 below).
