PATCH: Fix poor pointer math in devinet_sysctl_register

["Jordan Crouse" <jordan.crouse@amd.com>]

This patch fixes pointer math that under certain circumstances, results
in really bad pointers. This was encountered on a system compiled for i486, so
other compilers may differ, but I don't think it hurts anyone.
