hrtimer: Remove unused clock_base_next_timer_safe()

Browse Source 
clock_base_next_timer_safe() was added by commit a64ad57e41 ("hrtimer:
Simplify run_hrtimer_queues()") but has never had a caller; the queue
iteration in __hrtimer_run_queues() uses clock_base_next_timer() instead.

The two are functionally equivalent: struct hrtimer embeds the timerqueue
node at offset 0, so container_of() of a NULL node yields NULL.  Thus
clock_base_next_timer() already returns NULL on an empty queue and the
explicit NULL check in the _safe variant is redundant.

Being a static __always_inline function it does not trigger
-Wunused-function, so the dead code has gone unnoticed.  Remove it.

No functional change.
