sfc: Extend the legacy interrupt workarounds
Siena has two problems with legacy interrupts:
1. There is no synchronisation between the ISR read completion,
and the interrupt deassert message.
2. A downstream read at the "wrong" moment can return 0, and
suppress generating the next interrupt.
Falcon should suffer from both of these, and it appears it does.
Enable EFX_WORKAROUND_15783 on Falcon as well.
Also, when we see queues == 0, ensure we always schedule or rearm
every event queue.
