When processing request to add/replace user-defined element set, check of given element identifier and decision of numeric identifier is done in "__snd_ctl_add_replace()" helper function. When the result of check is wrong, the helper function returns error code. The error code shall be returned to userspace application.
Current implementation includes bug to return zero to userspace application regardless of the result. This commit fixes the bug.
