Set the right reportNextDraw

Bug: 8012229

mReportNextDraw is set by resized to have updateWindow() do
its thing. However if we are in updateWindow() and the
relayout() call to WindowManager wants us to report the draw
we should set reportNextDraw instead of mReportNextDraw
so that we report that frame instead of at the accidental next
invalidate.
