drm: rip out dev->ioctl_count tracking
Now dev->ioctl_count tries to prevent the device from disappearing if it's still in use. And if we'd actually need this code it would be hopelessly racy and broken. But luckily the vfs already takes care of this. So we can just rip it out. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Dave Airlie <airlied@redhat.com>
