UBIFS: slightly optimize write-buffer timer usage
This patch adds the following minor optimization: 1. If write-buffer does not use the timer, indicate it with the wbuf->no_timer variable, instead of using the wbuf->softlimit variable. This is better because wbuf->softlimit is of ktime_t type, and the ktime_to_ns function contains 64-bit multiplication. 2. Do not call the 'hrtimer_cancel()' function for write-buffers which do not use timers. 3. Do not cancel the timer in 'ubifs_put_super()' because the synchronization function does this. This patch also removes a confusing comment. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
