tipc: fix the timer expires after interval 100ms 

[ Upstream commit 6a7d8cff4a3301087dd139293e9bddcf63827282 ]

In the timer callback function tipc_sk_timeout(), we're trying to
reschedule another timeout to retransmit a setup request if destination
link is congested. But we use the incorrect timeout value
(msecs_to_jiffies(100)) instead of (jiffies + msecs_to_jiffies(100)),
so that the timer expires immediately, it's irrelevant for original
description.

In this commit we correct the timeout value in sk_reset_timer()
