garp: Fix vnet related panic for gratuitous arp

Gratuitous ARP packets are sent from a timer, which means we don't have a vnet
context set. As a result we panic trying to send the packet.

Set the vnet context based on the interface associated with the interface
address.

To reproduce:
sysctl net.link.ether.inet.garp_rexmit_count=2
ifconfig vtnet1 10.0.0.1/24 up
