[HOW] If cursor attributes or position are passed into DC via a stream update and we take the newer HWSS paths then it's possible that the update races with cursor offloading if it's enabled. This can cause the cursor to remain on the screen if no further updates come in if it results in HW cursor support being disabled. [HOW] Add the abort into the HWSS path so that cursor offloading doesn't attempt to reprogram the cursor with outdated params.
