pwm: stm32: Always program polarity

Browse source

Commit 7346e7a058 ("pwm: stm32: Always do lazy disabling") triggered a
regression where PWM polarity changes could be ignored.

stm32_pwm_set_polarity() was skipped due to a mismatch between the
cached pwm->state.polarity and the actual hardware state, leaving the
hardware polarity unchanged.
