driver: macvlan: Check if need rollback multicast setting in macvlan_open When dev_set_promiscuity failed in macvlan_open, it always invokes dev_set_allmulti without checking if necessary. Now check the IFF_ALLMULTI flag firstly before rollback the multicast setting in the error handler. Signed-off-by: Gao Feng <fgao@ikuai8.com> Signed-off-by: David S. Miller <davem@davemloft.net>
