drm/i915/fbc: Wait for vblank after FBC disable on glk+
On glk+ the hardware gets confused if we disable FBC while
it's recompressing and we perform a plane update during the
same frame. The result is that top of the screen gets corrupted.
We can avoid that by giving the hardware enough time to finish
the FBC disable before we touch the plane registers. Ie. we need
an extra vblank wait after FBC disable.
v2: Don't do the vblank wait if we never activated FBC in hw
