From: Geliang Tang <tanggeliang@kylinos.cn>

commit 5d13349472ac8abcbcb94407969aa0fdc2e1f1be upstream.

sk_reset_timer() was called twice in mptcp_pm_alloc_anno_list.

Simplify the code by using a 'goto' statement to eliminate the
duplication.

Note that this is not a fix, but it will help backporting the following
patch. The same "Fixes" tag has been added for this reason.

Fixes: 93f323b9cccc ("mptcp: add a new sysctl add_addr_timeout")

[ Before commit e4c28e3d5c09 ("mptcp: pm: move generic PM helpers to
  pm.c"), mptcp_pm_alloc_anno_list() was in pm_netlink.c. The same patch
  can be applied there without conflicts. ]
