irqflags: Explicitly ignore lockdep_hrtimer_exit() argument
When building with 'make W=1' but CONFIG_TRACE_IRQFLAGS=n, the
unused argument to lockdep_hrtimer_exit() causes a warning:
kernel/time/hrtimer.c:1655:14: error: variable 'expires_in_hardirq' set but not used [-Werror=unused-but-set-variable]
This is intentional behavior, so add a cast to void to shut up the warning.
Fixes: 73d20564e0dc ("hrtimer: Don't dereference the hrtimer pointer after the callback")
