drm/i915: Check framebuffer stride more thoroughly

Browse source

Make sure the the framebuffer stride is smaller than 32k. That
seems to be the limit on recent hardware. Not quite sure if
<=Gen4 has smaller limits.

Also when using a tiled memory make sure the object stride matches
the framebuffer stride.
