Phil Chang 5970a540da hrtimer: Prevent queuing of hrtimer without a function callback
[ Upstream commit 5a830bbce3af16833fe0092dec47b6dd30279825 ]

The hrtimer function callback must not be NULL. It has to be specified by
the call side but it is not validated by the hrtimer code. When a hrtimer
is queued without a function callback, the kernel crashes with a null
pointer dereference when trying to execute the callback in __run_hrtimer().

Introduce a validation before queuing the hrtimer in
hrtimer_start_range_ns().
