ASoC: rsnd: revert lock for calls to rsnd_dai_call
This reverts commit 'e9c390df671f ("ASoC: rsnd: make sure it uses lock when it calls rsnd_dai_call)' The additional locks make 1") lock issue when boot 2) lock issue when unbind/rmmod. And there is no problem without these locks. This patch revert it.
