hrtimer: Consolidate hrtimer_init() + hrtimer_init_sleeper() calls
hrtimer_init_sleeper() calls require prior initialisation of the hrtimer object which is embedded into the hrtimer_sleeper. Combine the initialization and spare a function call. Fixup all call sites. This is also a preparatory change for PREEMPT_RT to do hrtimer sleeper specific initializations of the embedded hrtimer without modifying any of the call sites. No functional change. [ anna-maria: Minor cleanups ] [ tglx: Adopted to the removal of the task argument of hrtimer_init_sleeper() and trivial polishing. Folded a fix from Stephen Rothwell for the vsoc code ] Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Anna-Maria Gleixner <anna-maria@linutronix.de> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Acked-by: Peter Zijlstra (Intel) <peterz@infradead.org> Link: https://lkml.kernel.org/r/20190726185752.887468908@linutronix.de
