WARN_ONCE() in the generic save_stack_trace_tsk_reliable() is superfluous.
The information is passed also via the return value. The only current
user klp_check_stack() writes its own warning when the reliable stack
traces are not supported. Other eventual users might want its own error
handling as well.
