bench: remove unnecessary & incorrect multiplication in MuHashDiv
Introduced in #19055, MuHashDiv benchmark used to multiply with a loop based on epochIterations. That does not do what it is supposed to do, because epochIterations() is determined automatically from nanobench. Also, multiplication is not needed for the algorithm (as pointed out by a comment in #19055), so it's better to remove this loop.
