Ben Hutchings 1646a6f352 sfc: Clean up test interrupt handling 
Interrupts are normally generated by the event queues, moderated by
timers.  However, they may also be triggered by detection of a 'fatal'
error condition (e.g. memory parity error) or by the host writing to
certain CSR fields as part of a self-test.

The IRQ level/index used for these on Falcon rev B0 and Siena is set
by the KER_INT_LEVE_SEL field and cached by the driver in
efx_nic::fatal_irq_level.  Since this value is also relevant to
self-tests rename the field to just 'irq_level'.

Avoid unnecessary cache traffic by using a per-channel 'last_irq_cpu'
field and only writing to the per-controller field when the interrupt
matches efx_nic::irq_level.  Remove the volatile qualifier and use
ACCESS_ONCE in the places we read these fields.
