ASoC: Intel: avs: Fix NULL ptr deref on rmmod

Browse Source 
When uloading snd_soc_avs module there is NULL pointer dereference.
It happens, because codec was moved into pdata and
avs_component_hda_unregister_dais() was not updated.

Fixes: 1581d5c682 ("ASoC: Intel: avs: boards: Add Kconfig option for obsolete card names")
