llist: survive cleared list better 
Make Curl_node_uremove() and Curl_node_take_elem() properly survive
run-time when the ->list field has been cleared previously. Like when
Curl_node_take_elem() is called twice.

We have asserts to catch those situations to make sure we avoid them if
we can, but if they still happen in a non-debug build we should make
sure the functions survive proper.

Pointed out by CodeSonar.
