sfc: Work around unreliable legacy interrupt status
In rare cases, reading the legacy interrupt status register can
acknowledge an event queue whose attention flag has not yet been set
in the register. Until we service this event queue it will not
generate any more interrupts. Therefore, as a secondary check, poll
the next slot in each active event queue whose flag is not set.
