ASoC: Intel: avs: Disable periods-elapsed work when closing PCM

Description
avs_dai_fe_shutdown() handles the shutdown procedure for HOST HDAudio stream while period-elapsed work services its IRQs. As the former frees the DAI's private context, these two operations shall be synchronized to avoid slab-use-after-free or worse errors.

Remediation
Red Hat statement
This is a use-after-free vulnerability in the Intel AVS audio driver that can cause kernel crashes during audio stream shutdown. The impact is limited to systems with Intel audio hardware using the AVS driver.
Red Hat mitigation
To mitigate this issue, prevent the snd_soc_avs module from being loaded. See https://access.redhat.com/solutions/41278 for instructions on how to blacklist a kernel module.
