KVM: x86: do not allow re-enabling quirks
Allowing arbitrary re-enabling of quirks puts a limit on what the quirks themselves can do, since you cannot assume that the quirk prevents a particular state. More important, it also prevents KVM from disabling a quirk at VM creation time, because userspace can always go back and re-enable that. Signed-off-by: Paolo Bonzini <[email protected]>
