Consolidate DZE_ActionInProgress and r_action_count to one variable

There is no point in having two variables for the same purpose.

It is also pointless to keep an action count tally like r_action_count
was doing, since it is only ever checked for being 0 or 1. Any count
higher or lower than that is irrelevant.

I will make this change in vanilla too.
