Use fast in-situ test for gate A20 being set, to cut down on the

number of (potentially very slow) gateA20_set operations.
Die with a fatal error if we are unable to set gate A20; if this fails

Always send EOI; do not chain to BIOS's default interrupt handler.

dumb PXE stack enables them.

Use net_device_operations structure and netdev_nullify() to allow for

safe dropping of the netdev ref by the driver while other refs still

Remove rx_quota; it wasn't used anywhere and added too much complexity
to implementing correct interrupt-masking behaviour in pxe_undi.c.
