interconnect: qcom: icc-rpm: Fix peak rate calculation 



Per the commit message of commit 'dd014803 ("interconnect: qcom:
icc-rpm: Add AB/IB calculations coefficients")', the peak rate should be
100/ib_percent. But, in what looks like a typical typo, the numerator
value is discarded in the calculation.

Update the implementation to match the described intention.
