i40e: clean zero-copy XDP Tx ring on shutdown/reset
When the zero-copy enabled XDP Tx ring is torn down, due to
configuration changes, outstanding frames on the hardware descriptor
ring are queued on the completion ring.
The completion ring has a back-pressure mechanism that will guarantee
that there is sufficient space on the ring.
