net/mlx5e: Update netdev txq on completions during closure
On sq closure when we free its descriptors, we should also update netdev
txq on completions which would not arrive. Otherwise if we reopen sqs
and attach them back, for example on fw fatal recovery flow, we may get
tx timeout.
Fixes: 29429f3300a3 ("net/mlx5e: Timeout if SQ doesn't flush during close")
