CRAS: input_data - Use offset for copy at buffer wrap
When input_data's circular buffer wraps, one buffer copy breaks
into two steps of smaller buffer copy. The second copy needs correct
offset.
Before this fix, there will be 8192/48000= 0.17 seconds periodic
clicking sound due to discontinuity.
BUG=chromium:882742
TEST=cras_test_client --capture_file /tmp/1 --effects aec
to record some loud sound, and listen to the recorded file to
verify there's no periodic clicking sound.
