Chris Wilson 931872fcea drm/i915: Check that plane/pipe is disabled before removing the fb 
Staring at an error state such as:

PGTBL_ER: 0x00000400
    Display B: Invalid tiling
fence[0] = 05001001
    valid, x-tiled, pitch: 512, start: 0x05000000, size: 1048576
Pinned [2]:
  00000000   131072 0001 0001 00000000 P uncached
  00020000  4096000 0041 0000 00000000 P uncached (name: 1)
Plane [1]:
  CNTR: c0000000 # enabled | gamma
  STRIDE: 00001400
  SIZE: 03ff04ff
  POS: 00000000
  ADDR: 05000000

Suggests that we did not clear the DSPBCNTR prior to unpinning the
framebuffer and reusing the GTT space. Impossible! Unless our DPMS
bookkeeping ran afoul again...

In the meantime add an assertion that the plane is decoupled from the
framebuffer prior to release.
