[Intel-wired-lan] [PATCH v3 iwl-net 5/8] ice: toggle netif_carrier when setting up XSK pool

[Maciej Fijalkowski]

This so we prevent Tx timeout issues. One of conditions checked on
running in the background dev_watchdog() is netif_carrier_ok(), so let
us turn it off when we disable the queues that belong to a q_vector
where XSK pool is being configured.
