hw-mgmt: thermal: Revert "Set pwm update worker immediate run only fo…

…r high PWM trend"

1. Revert change ""Set pwm update worker immediate run only for high PWM trend"
2. Removed error reading of psu{X}_fan1_speed_get from error cases
TC not using psu1_fan1_speed_get value in PWM calculation. TC only shows
PSU FAN speed "just for information" in the log and should not be considered as thermal  error case.
