Subject: be2net: don't delete MAC on close on unprivileged BE3 VFs

From: Ivan Vecera <cera@cera.cz>


[ Upstream commit 6d928ae590c8d58cfd5cca997d54394de139cbb7 ]

BE3 VFs without FILTMGMT privilege are not allowed to modify its MAC,
VLAN table and UC/MC lists. So don't try to delete MAC on such VFs.
