team: move dev_mc_sync after master_upper_dev_link in team_port_add
The same fix as in 'bonding: move dev_mc_sync after master_upper_dev_link
in bond_enslave' is needed for team driver.
The panic can be reproduced easily:
ip link add team1 type team
ip link set team1 up
ip link add link team1 vlan1 type vlan id 80
ip link set vlan1 master team1
Fixes: cb41c997d444 ("team: team should sync the port's uc/mc addrs when add a port")
