cpufreq: interactive: Don't set floor_validate_time during boost
Frequency selection algorithm guarantees its chosen frequency
is not lower than hispeed_freq as long as boost is enabled.
Setting floor_freq and floor_validate_time during boost could block
CPU frequency from going below hispeed_freq even after
boostpulse_duration expires, if min_sample_time is higher than
boostpulse_duration. This conflicts with the intention of commit
de091367ead15b6e95dd1d0743a18f0da5a07ee5
(cpufreq: interactive: specify duration of CPU speed boost pulse)
to allow CPU to ramp down immediately after boost expires. It also
makes boost behavior inconsistent since it depends on min_sample_time.
Avoid setting floor_freq and floor_validate_time when boost starts.
