Profiler: Use profile length in ms as histogram column count directly
Beforehand we were dividing the frame width by the profile length in ms and then dividing the frame width by the result once more, which is equivalent to (but slower) just using the length in ms directly, aside from the case in which the profile is less than 1 ms long, in which case this would trigger undefined behaviour due to the division by zero
