Subject: [PATCH] ALSA: echoaudio: Deletion of a check before
 release_and_free_resource()

The release_and_free_resource() function tests whether its argument is NULL
and then returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
