server/red_worker: fix worker->drawable_count

Browse Source 
drawable_count was becoming negative. It tracks the number of
items in the worker->current_list ring. It was decremented correctly,
but incremented only in several cases. The cases it wasn't incremented
where:
 red_current_add_equal found an equivalent drawable
by moving the increment to where the item is added to current_list, in
__current_add_drawable, the accounting remains correct.

This has no affect other then correct accounting, as drawable_count isn't
used for anything.
