KVM: x86: Propagate AMD's IbrsSameMode to the guest
If IBRS provides same mode (kernel/user or host/guest) protection on the
host, then by definition it also provides same mode protection in the
guest. In fact, all different modes from the guest's perspective are the
same mode from the host's perspective anyway.
Propagate IbrsSameMode to the guests.
