Subject: [PATCH AUTOSEL 4.14 368/371] tipc: fix wrong timeout input for tipc_wait_for_cond()

From: Tung Nguyen <tung.q.nguyen@...tech.com.au>

[ Upstream commit 12db3c8083fcab4270866a88191933f2d9f24f89 ]

In function __tipc_shutdown(), the timeout value passed to
tipc_wait_for_cond() is not jiffies.

This commit fixes it by converting that value from milliseconds
to jiffies.

Fixes: 365ad353c256 ("tipc: reduce risk of user starvation during link congestion")
