emerg call deny: fix RR release cause
So far the we indicated pre-emption in the release cause of denying an
emergency setup, instead indicate protocol error.
When emergency calls are disallowed, it is not pre-emption (making room
for an emergency call) but a protocol error (MS asks for emergency call
when the network does not allow it).
