David Gibson a2eb2d310a Add helpers for normal inbound packet destination addresses
tap_ip_send() doesn't take a destination address, because it's specifically
for inbound packets, and the IP addresses of the guest/namespace are
already known to us.  Rather than open-coding this destination address
logic, make helper functions for it which will enable some later cleanups.
