net: ena: fix: Free napi resources when ena_up() fails
BugLink: https://bugs.launchpad.net/bugs/1850175 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().
