Currently we destroy inet devices when we remove the last interface
from an inet device, and during NETDEV_UNREGISTER. We only create
them during NETDEV_REGISTER event. The result is if you and an ipv4
address to a device delete it (so the device has no ipv4 addresses)
and attampt to add any ipv4 address to that device you will receive
an -ENOBUFS error.
To correct the problem this patch simply deletes the excess inet
device destroy.
