When going into suspend, the HW configuration for MSI-X will
likely be lost. As a consequence, after waking up, all IRQ
causes will be mapped to interrupt 0, and as a consequence we
don't notice the interrupt because in most cases this is an
interrupt for a queue, and getting it doesn't read the other
cause registers.
