[PATCH 2/2] team: fix memory leak

[Pan Bian]

In function team_nl_send_options_get(), pointer skb keeps the return
value of function nlmsg_new(). When the call to genlmsg_put() fails, the
control flow directly returns and does not free skb. This will result in
a memory leak bug. This patch fixes it.
