Using the MMU to track writes to VRAM should only be needed when the FIFO is
disabled. When the FIFO is enabled (SVGA_REG_CONFIG_DONE = 1), the guest will
notify the host via the FIFO when it has written to a region of VRAM directly,
using the SVGA_CMD_UPDATE FIFO command.
Unless I'm confused, this change appears to use the MMU to track VRAM updates
unconditionally.
