Subject: [PATCH net 4/8] mptcp: remove duplicate sk_reset_timer call

From: Geliang Tang <tanggeliang@...inos.cn>

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")
