[PATCH RFC net-next 16/34] jump_label: export static_key_slow_{inc,dec}_cpuslocked()

[Alexander Lobakin]

Sometimes, there's a need to modify a lot of static keys or modify the
same key multiple times in a loop. In that case, it seems more optimal
to lock cpu_read_lock once and then call _cpuslocked() variants.
The enable/disable functions are already exported, the refcounted
counterparts however are not. Fix that to allow modules to save some
cycles.
