smart_amp_test: process same frames from all inputs 

The smart amp test module will first process feedback if
presents, and then process main input to its output.

However, minimum available frames from main input and
feedback is used in processing feedback, while available
frames from main input is used in processing main input.
The different frames of audio data could be processed from
main input buffer and feedback buffer.

This patch make sure the same number of frames are processed
from main input and feedback buffers.

Fixes: #7184
