[RFC][PATCH v3 30/33] timers: jbd2: Use timer_shutdown() before freeing timer

[Steven Rostedt]

From: "Steven Rostedt (Google)" <rostedt@xxxxxxxxxxx>

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().
