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.
