Subject: [PATCH v4a 26/38] timers: jbd2: Use timer_shutdown() before freeing timer

From: "Steven Rostedt (Google)" <rostedt@...dmis.org>

Before a timer is freed, timer_shutdown() must be called. Note that it is
assumed that the timer is not running while being freed, so only
timer_shutdown() is used, and not timer_shutdown_sync().
