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: cb41c997 ("team: team should sync the port's uc/mc addrs when add a port")
