[PATCH] hrtimer: Remove comment saying HRTIMER_SOFTIRQ is unused.

[Sebastian Andrzej Siewior]

The comment is obsolete since commit

  5da70160462e8 ("hrtimer: Implement support for softirq based hrtimers")

because it is possible to let a specific hrtimer expire in softirq
context.

Remove the obsolete comment.
