drm/i915: Use plane->state->fb in watermark code (v2)
plane->fb is a legacy pointer that not always be up-to-date (or updated
early enough). Make sure the watermark code uses plane->state->fb so
that we're always doing our calculations based on the correct
framebuffers.
This patch was generated by Coccinelle with the following semantic
patch:

struct drm_plane *P;

- P->fb
+ P->state->fb
v2: Rebase
