#     powerpc/xive: Discard ESB load value when interrupt is invalid
#     
#     A load on an ESB page returning all 1's means that the underlying
#     device has invalidated the access to the PQ state of the interrupt
#     through mmio. It may happen, for example when querying a PHB interrupt
#     while the PHB is in an error state.
#     
#     In that case, we should consider the interrupt to be invalid when
#     checking its state in the irq_get_irqchip_state() handler.
#     
#     Fixes: da15c03b047d ("powerpc/xive: Implement get_irqchip_state method for XIVE to fix shutdown race")
