KVM: s390: clear the pfault queue if user space sets the invalid token
We need a way to clear the async pfault queue from user space (e.g.
for resets and SIGP SET ARCHITECTURE).
This patch simply clears the queue as soon as user space sets the
invalid pfault token. The definition of the invalid token is moved
to uapi.
