ALSA: hda/hdmi: always check pin power status in i915 pin fixup
When system is suspended with active audio playback to HDMI/DP, two
alternative sequences can happen at resume:
a) monitor is detected first and ALSA prepare follows normal
stream setup sequence, or
b) ALSA prepare is called first, but monitor is not yet detected,
so PCM is restarted without a pin,
In case of (b), on i915 systems, haswell_verify_D0() is not called at
resume and the pin power state may be incorrect. Result is lack of audio
after resume with no error reported back to user-space.
Fix the problem by always verifying converter and pin state in the
i915_pin_cvt_fixup().
