hrtimer: Rename __hrtimer_hres_active() to hrtimer_hres_active()
[ Upstream commit b7c8e1f8a7b4352c1d0b4310686385e3cf6c104a ]
The function hrtimer_hres_active() are defined in the hrtimer.c file, but
not called elsewhere, so rename __hrtimer_hres_active() to
hrtimer_hres_active() and remove the old hrtimer_hres_active() function.
kernel/time/hrtimer.c:653:19: warning: unused function 'hrtimer_hres_active'.
Fixes: 82ccdf062a64 ("hrtimer: Remove unused function")
