VMM: Fixed random memory corruption and XMM register state corruption inside the VM when Hyper-V is used (bug #19695)

This could be a very important fix for users with Windows 10 pro or Windows 10 enterprise, Hyper-V installed and enabled.
When the fix is working you don't have to disable Hyper-V any longer to run VBox-tasks for LHC@home and other projects using VirtualBox.
Please test and confirm.

I though that it was not good practice to install several hypervisor on the same host.... ?
or was it only a problem of sharing memory ?
