net: ena: fix: Free napi resources when ena_up() fails

Browse source

ena_up() calls ena_init_napi() but does not call ena_del_napi() in
case of failure. This causes a segmentation fault upon rmmod when
netif_napi_del() is called. Fix this bug by calling ena_del_napi()
before returning error from ena_up().
