nat: Fix a crash when a BSC disconnects while a rejected IMSI
When we reject the IMSI we do not have the msc_con set on the
SCCP connection, but we do have a remote_ref. So the nat_send_rlsd
will end up with a crash due the msc_con being zero. Fix the
crash by only sending a released to the MSC when the connection
is not local.
