sched: don't inflate the task load when the CPU max freq is restricted
When the CPU max freq is restricted and the CPU is running at the
max freq, the task load is inflated by max_possible_freq/max_freq
factor. This results in tasks migrating early to the better capacity
CPUs which makes things worse if the frequency restriction is due
to the thermal condition.
