raid5: Don't set read-ahead when there is no queue
dm-raid456 does not provide a 'queue' for raid5 to use,
so we must make raid5 stop depending on the queue.
First: read_ahead
dm handles read-ahead adjustment fully in userspace, so
simply don't do any readahead adjustments if there is
no queue.
Also re-arrange code slightly so all the accesses to ->queue are
together.
Finally, move the blk_queue_merge_bvec function into the 'if' as
the ->split_io setting in dm-raid456 has the same effect.
