bsc: Fix crash when the new route is not available

When we are asked to route calls on a local link and
the link is not available we would crash when trying
to send a packet over a deadline. When we have decided
to move a connection it is guranteed that the current
SCCP connection will vanish, we either migrate to another
MSC or the RSL/subscriber connection will be closed.
