drm/i915: annotate maybe unused but set intel_plane_state variables

Browse Source 
Prepare for re-enabling -Wunused-but-set-variable.

for_each_new_intel_plane_in_state() requires passing in a struct
intel_plane_state pointer, which it uses, but in many places this leads
to warning about unused but set variables. Annotate them with
__maybe_unused.
