KVM: PPC: Book3S HV nestedv2: Do not cancel pending decrementer exception
In the nestedv2 case, if there is a pending decrementer exception, the
L1 must get the L2's timebase from the L0 to see if the exception should
be cancelled. This adds the overhead of a H_GUEST_GET_STATE call to the
likely case in which the decrementer should not be cancelled.
Avoid this logic for the nestedv2 case.
