VMware VGA: Only enable dirty log tracking when fifo is disabled

This patch enables dirty log tracking whenever it's needed and disables it
when it is not.

We unconditionally enable dirty log tracking on reset, restart dirty log
tracking when PCI IO regions are remapped, and disable/enable it based on
commands from the guest.
