Do not allow the use of the loopback interface in netmap.

Description

Do not allow the use of the loopback interface in netmap.

The generic support in netmap send the packets using if_transmit() and the
loopback do not support packets coming from if_transmit()/if_start().

This avoids the use of the loopback interface and the subsequent crash that
happens when the application send packets to the loopback interface.
