i40e: refactor Rx filter handling
Properly track filter adds and deletes so the driver doesn't lose filters during resets and up/down cycles. Add a tracking mechanism so that the driver knows when to enter and leave promiscuous mode. Implement a simple state machine so the driver can track the status of each filter throughout its lifecycle. Properly manage the overflow promiscuous state for the each VSI, and provide a way for the driver to detect when to exit overflow promiscuous mode. Remove all possible default MAC filters that the firmware may have set up so that the driver can manage these correctly, particularly when VLANs come into play. Remove the LAA flag for filters; instead just send whatever we get through set_mac to the firmware as the LAA for wakeup purposes. Finally, add the state of each filter to debugfs output so we can see what's going on inside the driver's pointy little head.
