mlock, mlock2, munlock: Tell the compiler we don't dereference the pointer

Browse Source 
Since https://gcc.gnu.org/r11-959, the compiler emits
-Wmaybe-uninitialized if a const pointer to an uninitialized buffer is
passed.  Tell the compiler we don't dereference the pointer to remove
the false alarm.
