drm/i915: Make use of intel_fb_obj() (v2)
This should hopefully simplify the display code slightly and also
solves at least one mistake in intel_pipe_set_base() where
to_intel_framebuffer(fb)->obj is referenced during local variable
initialization, before 'if (!fb)' gets checked.
Potential uses of this macro were identified via the following
Coccinelle patch:
@@
expression E;
@@
* to_intel_framebuffer(E)->obj
@@
expression E;
identifier I;
@@
I = to_intel_framebuffer(E);
...
* I->obj
v2: Rewrite some NULL tests in terms of the obj rather than the fb.
Also add a WARN() if trying to pageflip with a disabled primary
plane. [Suggested by Chris Wilson]
