md/raid5: need_this_block: start simplifying the last two conditions. Both the last two cases are only relevant if something has failed and something needs to be written (but not over-written), and if it is OK to pre-read blocks at this point. So factor out those tests and explain them. Signed-off-by: NeilBrown <neilb@suse.de>
