PCSX2-Counters: Fix rounding of blank and render 

I guess the intention of the older logic was to get the truncated part
by comparing with the original value, but that went wrong due to using
the pre-normalized value (before the division) for comparison.

Hence let's just do a modulo for rounding the render and blank.
