neighbour: Drop read_lock_bh(&tbl->lock) in pneigh_lookup().

Now, all callers of pneigh_lookup() are under RCU, and the read
lock there is no longer needed.

Let's drop the lock, inline __pneigh_lookup_1() to pneigh_lookup(),
and call it from pneigh_create().

The next patch will remove tbl->lock from pneigh_create().
