virtualbox guest additions assert

ReactOS hits an assert when you shutdown it after having VirtualBox Guest
Additions installed.

steps to reproduce:

1.- install VBox Guest Additions
2.- Change to 32-bit color depth
3.- Once rebooted, shutdown ReactOS

It will crash

For Michael Martin:

"Just glancing at the assert, I think that the vbox video driver that got
installed was for made for win2008, in which MmFreeContiguousMemory can be
called at IRQL<=DISPATCH_LEVEL. In reactos we Are using PAGED_CODE, which
causes the assert. We should remove it as we are shooting for win2008.
