rbd: mark block queue as non-rotational
Set QUEUE_FLAG_NONROT. Following commit b277da0a8a59 ("block: disable entropy contributions for nonrot devices") we should also clear QUEUE_FLAG_ADD_RANDOM, but it's off by default for blk-mq drivers, so just note it in the comment. Also remove physical block size assignment - no sense in repeating defaults that are not going to change. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
