raid6/async_tx: handle holes in block list in async_syndrome_val
async_syndrome_val check the P and Q blocks used for RAID6 calculations. With DDF raid6, some of the data blocks might be NULL, so this needs to be handled in the same way that async_gen_syndrome handles it. As async_syndrome_val calls async_xor, also enhance async_xor to detect and skip NULL blocks in the list. Signed-off-by: NeilBrown <neilb@suse.de>
