ASoC: SOF: Intel: hda: fix warnings during FW load
[ Upstream commit 4ff5f6439fe69624e8f7d559915e9b54a6477684 ]
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().
