ASoC: Intel: avs: Fix module lookup 

commit ff04437f6d upstream.

When changing value of kcontrol, FW module to which data should be send
needs to be found. Currently it is done in improper way, fix it. Change
function name to indicate that it looks only for volume module.

This allows to change volume during runtime, instead of only changing
init value.
