audio: host: reload DMA buffer on non-zero partial_size 

This patch ensures that the DMA buffer is reloaded when
partial_size is non-zero, even if copy_bytes is zero.
This condition typically occurs at the end of a stream,
where the last data chunk does not meet the condition
for reload DMA buffer, leaving a non-zero partial_size.
