Split arpresolve() into fast/slow path.

This change isolates the most common case (e.g. successful lookup)
  from more complicates scenarios. It also (tries to) make code
  more simple by avoiding retry: cycle.

The actual goal is to prepare code to the upcoming change that will
  allow LL address retrieval without acquiring LLE lock at all.
