Make all active CRTCs scan out an all-black framebuffer in LeaveVT
And destroy all other FBs. This is so that other DRM masters can only
get access to this all-black FB, not to any other FB we created, while
we're switched away and not DRM master.
Fixes: b09fde0d81e0 ("Use reference counting for tracking KMS
framebuffer lifetimes")
