[PATCH 3.16 207/366] team: fix netconsole setup over team

[Ben Hutchings]

3.16.60-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Xin Long <lucien.xin@xxxxxxxxx>

commit 9cf2f437ca5b39828984064fad213e68fc17ef11 upstream.

The same fix in Commit dbe173079ab5 ("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: 0fb52a27a04a ("team: cleanup netpoll clode")
