Revert "vm/windows: Exit if VM has dropped out".

This reverts commit 457f2c2835e88dfda11f04dcbb27a918a47f662b.

Damn, this commit wasn't supposed to hit the stable branch yet, and I
accidentally pushed this because I was in the wrong working dir. It
doesn't break anything but fixes nothing, that's why I'm reverting until
the proper fix is ready and tested.

Sorry everyone for the noise X-/
