[PATCH 1/4] echo-cancel: Fix apply_diff_time() to use correct sample spec

[pmeerw@xxxxxxxxxx (Peter Meerwald)]

From: Stefan Huber <s.huber@xxxxxxxxxxxxxxxxxx>

apply_diff_time() fails when dropping bytes from the playback stream
and the sample spec of sink and source differ as source's sample spec is
used. Fix this by using sink's sample spec.
