Subject: [PATCH net-next 1/2] mptcp: use nlmsg_free instead of kfree_skb

From: Geliang Tang <geliang.tang@...e.com>

Use nlmsg_free() instead of kfree_skb() in pm_netlink.c.

The SKB's have been created by nlmsg_new(). The proper cleaning way
should then be done with nlmsg_free().

For the moment, nlmsg_free() is simply calling kfree_skb() so we don't
change the behaviour here.
