[PATCH] hrtimer: Remove the comment about not used HRTIMER_SOFTIRQ

[Sebastian Andrzej Siewior]

The softirq `HRTIMER_SOFTIRQ' was not used since commit
  c6eb3f70d448 ("hrtimer: Get rid of hrtimer softirq")

but then we started using it again, beginning with commit
  5da70160462e ("hrtimer: Implement support for softirq based hrtimers")

so the comment is not longer accurate.

Remove the comment saying that HRTIMER_SOFTIRQ not used.
