Botond Dénes 27fbca84f6 reader_concurrency_semaphore: remove prethrow_action ...

The semaphore accepts a functor as in its constructor which is run just
before throwing on wait queue overload. This is used exclusively to bump
a counter in the database::stats, which counts queue overloads. However,
there is now an identical counter in
reader_concurrency_semaphore::stats, so the database can just use that
directly and we can retire the now unused prethrow action.
