KVM: PPC: Book3S: PR: Fix signal check race
As Scott put it:
> If we get a signal after the check, we want to be sure that we don't

> will cause another signal check.
we need to have interrupts disabled from the point we do signal_check()
all the way until we actually enter the guest.
This patch fixes potential signal loss races.
