If the user has specified their own RSS hash key, don't
lose it across queue resets such as DOWN/UP, MTU change,
and number of channels change. This is fixed by moving
the key initialization to a little earlier in the lif
creation.
Also, let's clean up the RSS config a little better on
the way down by setting it all to 0.

The ionic interrupt model is based on interrupt control blocks
accessed through the PCI BAR. Doorbell registers are used by
the driver to signal to the NIC that requests are waiting on
the message queues. Interrupts are used by the NIC to signal
to the driver that answers are waiting on the completion queues.
