Revert "audio: exclude the echo reference device in capture position test"

This reverts commit b22f307ccfd1072e3d61deb4e03659db7a168b7d.

Reason for revert: As explained in b/192307382#comment12, the HAL must provide capture positions for the echo reference input regardless of whether there is any actual output.

This should not affect O6/R4 as according to b/192307382#comment10, the VTS tests pass w/o this patch after the HAL has been fixed.
