ASoC: hdac_hda: fix race in device removal When ASoC card instance is removed containing a HDA codec, hdac_hda_codec_remove() may run in parallel with codec resume. This will cause problems if the HDA link is freed with snd_hdac_ext_bus_link_put() while the codec is still in middle of its resume process. To fix this, change the order such that pm_runtime_disable() is called before the link is freed. This will ensure any pending runtime PM action is completed before proceeding to free the link. This issue can be easily hit with e.g. SOF driver by loading and unloading the drivers.
