Subject: [PATCH 1/4] [IPV4]: Only panic if inetdev_init fails for loopback

[IPV4]: Only panic if inetdev_init fails for loopback

When I made the inetdev_init call work on all devices I incorrectly
left in the panic call as well.  It is obviously undesirable to
panic on an allocation failure for a normal network device.  This
patch moves the panic call under the loopback if clause.
