Kuniyuki Iwashima dc2a27e524 neighbour: Update pneigh_entry in pneigh_create(). ...

neigh_add() updates pneigh_entry() found or created by pneigh_create().

This update is serialised by RTNL, but we will remove it.

Let's move the update part to pneigh_create() and make it return errno
instead of a pointer of pneigh_entry.

Now, the pneigh code is RTNL free.
