ipa: Use VTY-configured default network indicator

When we receive a message from an IPA/SCCPlite connection, we only
have SCCP global titles and no underlying M3UA.  We since have
to introduce a fake M3UA header.  While we correctly set the SI,
OPC and DPC, we didn't set the NI to what is configured as default
for the cs7 instance in the VTY.  For international, this problem
was hidden by the fact that international is '0' and hence our
default memory initialization.
