fix: $request_ref->{count} not used (#6914)

$request_ref->{count} shows up 4 times in the code. Though it never
appears to be used as three of the times that it appears it is only to
define it. The remaining instance that it appears such that it is
referenced, does not seem to benefit from the previous three instances
where the value is defined. As such this appears to be unused. This
commit removes all four instances.
