drm/vmwgfx: Make fence sequences continous across a VT switch.
A vt switch in stealth mode would take down the FIFO, and re- initialize fence sequence numbers. This patch saves the current state of the fence sequence when the FIFO is disabled. Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
