Currently userspace is allowed to feed in any king of garbage in the
high bits of the mode flags/type, as are drivers when probing modes.
Reject any mode with bogus flags/type.
Hopefully this won't break any current userspace...
Unfortunately this breaks xf86-video-vmware which currently leaves the
mode->type uninitialized :(.
That code is inherited from the old gallium xorg state tracker. I don't
know whether it has spread elsewhere but the symptoms are that the X
server frequently dies failing to set screen resources, a very
uninformative error.
I'll fix the xf86-video-vmware driver, but I guess we need to back out
the mode->type check.
