ASoC: SOF: Intel: hda: fix warnings during FW load
The "snd_pcm_substream" handle was not initialized properly in hda-loader.c for firmware load. When the HDA DMAs were used to load the firmware, the interrupts related to firmware load also triggered calls to snd_sof_pcm_period_elapsed() on a non-existent ALSA PCM stream. This caused runtime kernel warnings from pcm_lib.c:snd_pcm_period_elapsed().
