kvm: x86: disable the narrow guest module parameter on unload
When the kvm_intel module unloads the module parameter 'allow_smaller_maxphyaddr' is not cleared because the backing variable is defined in the kvm module. As a result, if the module parameter's state was set before kvm_intel unloads, it will also be set when it reloads. Explicitly clear the state in vmx_exit() to prevent this from happening.
