intel: Simplify stencil detiling arithmetic
When calculating the y offset needed for detiling window system stencil buffers, replace the term region->height * 2 + region->height % 2 - 1 with rb->Height - 1 . The two terms are incidentally equivalent due to some out-of-date, incorrect code in the Intel DRI2 glue for DDX. (See intel_process_dri2_buffer_with_separate_stencil(), line ``buffer_height /= 2;``). Note: This is a candidate for the 7.11 branch (only the intel_span.c hunk).
