powerpc/kvm: Fix kvmppc_core_pending_dec
The vcpu->arch.pending_exceptions field is a bitfield indexed by
interrupt priority number as returned by kvmppc_book3s_vec2irqprio.
However, kvmppc_core_pending_dec was using an interrupt vector shifted
by 7 as the bit index. Fix it to use the irqprio value for the
decrementer interrupt instead. This problem was found by code
inspection.
