If cache is enabled, objects will be retrieved/put from/to cache,
subsequently from/to the common pool. Now the debug stats calculate
the objects retrieved/put from/to cache and pool together, it is
better to distinguish them.

I think we should only have the common_pool stats here, for 2 reasons:

- more consistent with put()
- in case we are called by __mempool_generic_get() for a "backfill"
  operation, the number of successes will not be incremented by the
  correct value (the "req" variable is != n)

This one was forgotten, there is a compilation error:
