Fix potential null pointer dereference.
When the compiler does not perform return value optimization, the
LockPtr<> destructor of the temporary object is called after the move
constructor has set the Lock to null, thus causing a null pointer
dereference in the destructor. This can be replicated using the
-fno-elide-constructors build flag.
