Fix inconsistent irq status, because of this in the trace logs, for e.g.
LSI status was 0x7, i.e. XICS_STATUS_ASSERTED, XICS_STATUS_SENT and
XICS_STATUS_REJECTED all set, which did not make sense. So the REJECTED
would have been set in earlier interrupt cycle, and then asserted and
sent in this current one.
