ALSA: hda - hdmi get jack from hda_jack_tbl when not dyn_pcm_assign

On Intel platform, if !dyn_pcm_assign, spec->pcm_rec[].jack is not
NULL even after snd_hda_jack_tbl_clear() is called to free snd_jack.
This may cause access invalid memory when calling snd_jack_report.

Fixes: 25e4abb33df3 ('ALSA: hda - hdmi jack created based on pcm')
