[PATCH 6.12.y] mptcp: remove duplicate sk_reset_timer call

[Sasha Levin <sashal@kernel.org>]

From: Geliang Tang <geliang@kernel.org>

[ Upstream commit 5d13349472ac8abcbcb94407969aa0fdc2e1f1be ]

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")
