Subject: [PATCH iwl-net 1/2] ice: Fix link_down_on_close message

From: Katarzyna Wieczerzycka <katarzyna.wieczerzycka@...el.com>

The driver should not report an error message when for a medialess port
the link_down_on_close flag is enabled and the physical link cannot be
set down.

Fixes: 8ac7132704f3 ("ice: Fix interface being down after reset with link-down-on-close flag on")
