block: introduce blk_queue_rot()
To check if a request queue is for a rotational device, a double
negation is needed with the pattern "!blk_queue_nonrot(q)". Simplify
this with the introduction of the helper blk_queue_rot() which tests
if a requests queue limit has the BLK_FEAT_ROTATIONAL feature set.
All call sites of blk_queue_nonrot() are modified to use blk_queue_rot()
and blk_queue_nonrot() definition removed.
No functional changes.
