net: ena: don't wake up tx queue when down

BugLink: https://bugs.launchpad.net/bugs/1850175

There is a race condition that can occur when calling ena_down().
The ena_clean_tx_irq() - which is a part of the napi handler -
function might wake up the tx queue when the queue is supposed
to be down (during recovery or changing the size of the queues
for example) This causes the ena_start_xmit() function to trigger
and possibly try to access the destroyed queues.

The race is illustrated below:

Flow A: Flow B(napi handler)
ena_down()
   netif_carrier_off()
   netif_tx_disable()
                                                      ena_clean_tx_irq()
                                                         netif_tx_wake_queue()
   ena_napi_disable_all()
   ena_destroy_all_io_queues()

After these flows the tx queue is active and ena_start_xmit() accesses
the destroyed queue which leads to a kernel panic.

Revert "net: ena: ethtool: add extra properties retrieval via get_priv_flags"

BugLink: https://bugs.launchpad.net/bugs/1850175

This reverts commit 315c28d2b714 ("net: ena: ethtool: add extra properties retrieval via get_priv_flags").

As discussed at netconf and on the mailing list we can't allow
for the the abuse of private flags for exposing arbitrary device
labels.

net: ena: Fix bug where ring allocation backoff stopped too late

BugLink: https://bugs.launchpad.net/bugs/1850175

The current code of create_queues_with_size_backoff() allows the ring size
to become as small as ENA_MIN_RING_SIZE/2. This is a bug since we don't
want the queue ring to be smaller than ENA_MIN_RING_SIZE

In this commit we change the loop's termination condition to look at the
queue size of the next iteration instead of that of the current one,
so that the minimal queue size again becomes ENA_MIN_RING_SIZE.
