team: fix netconsole setup over team

Browse source 
[ Upstream commit 9cf2f437ca5b39828984064fad213e68fc17ef11 ]

The same fix in Commit dbe173079a ("bridge: fix netconsole
setup over bridge") is also needed for team driver.

While at it, remove the unnecessary parameter *team from
team_port_enable_netpoll().

v1->v2:
  - fix it in a better way, as does bridge.

Fixes: 0fb52a27a0 ("team: cleanup netpoll clode")
