[IPV4]: Cleanup the devinet_sysctl_register
I moved the call to kmalloc() from the *t declaration into
the code (this is confusing when a variable is initialized
with the result of some call) and removed unneeded comment
near the error path. Just like I did with the neigh ctl-s.
Besides, I fixed the goto's and the labels - they were indented
with spaces :(
