Saurabh Shah 7a606847a6 hwc: Update rotator object handling in error cases 
Earlier, on configuration errors, we simply drained the fences held
by current rotator objects and went to GPU comp. The rotator objects
were deleted in the subsequent rounds, if they remained unused.

If we don't use GPU comp on failure but use other strategies, then we
need to mark the rotator objects for a display for reuse, so that
other strategies can use them.

Also any failure resets on overlay or rotator need to happen from
functions that call configuration helpers rather than the helper
themselves. Leaving cleanup to black-box helpers is not desirable.
