selftests: ALSA: pcmtest: Compare all captured bytes in ni_capture

Browse Source 
The ni_capture test reads rate * time frames into each channel buffer
and then compares rate * time bytes. A frame is sample_size bytes per
channel, so with S16_LE only the first half of each channel is checked.
If the second half is wrong the test still passes.

Compare rate * time * sample_size bytes per channel.
