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.
