block: introduce bdev_rot()
Introduce the helper function bdev_rot() to test if a block device is a
rotational one. The existing function bdev_nonrot() which tests for the
opposite condition is redefined using this new helper.
This avoids the double negation (operator and name) that appears when
testing if a block device is a rotational device, thus making the code a
little easier to read.
Call sites of bdev_nonrot() in the block layer are updated to use this
new helper. Remaining users in other subsystems are left unchanged for
now.
