        src/sys/netinet: ip_output.c

Log Message:
Fix panic on packet sending via a route with rt_ifa of AF_LINK.

A route with rt_ifa of AF_LINK can be set by some routing daemons when
it adds a route that has a gateway of AF_LINK.  If there is no address on
a target interface, the kernel sets an AF_LINK address of the interface to
rt_ifa of the route.  In that case, a variable of a local address in
ip_output (ia) can be NULL and we need more NULL-checks of it.
