Mitch Williams e284fc88df i40evf: delay releasing rings
When the VF interface is closed, we cannot immediately free our rings
and RX buffers, because the hardware hasn't yet stopped accessing this
memory. This shows up as a panic or memory corruption when the device is
brought down while under heavy stress.

To fix this, delay releasing resources until we receive acknowledgment
from the PF driver that the rings have indeed been stopped. Because of
this delay, we also need to check to make sure that all of our admin
queue requests have been handled before allowing the device to be
opened.
