Older KVM versions save CS dpl value to an invalid value for real mode guests
(0x3). This patch detect this situation when loading CPU state and set all the
segments dpl to zero.
This will allow migration from older KVM on host without unrestricted guest
to hosts with restricted guest support.

As discussed offlist, I would prefer to have this in the kernel since
that's where the bug is. Gleb disagrees.
As this is a migration bug I prefer to fix it in the migration code only.
Fixing it in the kernel will effect all scenarios that
