cpufreq: qcom: Update the scheduler of throttle removal

There can be a case where the frequency at the time of throttle removal
was not the max frequency. Thus the scheduler update sent would not be
the max frequency, which would result in wrong capacity calculation,
even though the CPU frequency is bumped to max frequency later.

Thus update the scheduler with the cpuinfo max frequency before enabling
the throttle IRQ.
