Since bf20ab538c81 ("blk-throttle: remove CONFIG_BLK_DEV_THROTTLING_LOW"),
the throttle slice time differs between SSD and non-SSD devices. This
causes test failures with slow throttle speeds on SSD devices.

The first patch in the series fixes the problem by restoring the throttle
slice time to a fixed value, matching behavior seen prior to above
mentioned revert. The second patch is optional and replaces the
throtl_slice variable with a constant.
