From: Maciej Fijalkowski <maciej.fijalkowski@xxxxxxxxx>
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. Turn carrier on in ice_qp_ena()
only when ice_get_link_status() tells us that physical link is up.
Fixes: 2d4238f55697 ("ice: Add support for AF_XDP")
