test/linked_list: silence nonsense warnings

Browse Source 
../misc/linked_list.h:71:34: warning: the address of ‘e6’ will always
evaluate as ‘true’ [-Waddress]

No shit, e6 is on the stack. But the macro argument is also allowed to
be NULL. Add some dumb nonsense to shut up the useless warning. (It's
probably useful in other contexts though, so don't disable it
completely.)
