    ip6: Fix crash in ip6_output with debug enabled
    
    It turns out the crash only occurs if LWIP_DEBUG is enabled. If the
    parameter dest is NULL the function tries to find a route using the
    destination address of the packet instead. If this fails as well a
    debug message is printed but it is still using dest causing a NULL
    pointer dereference and crash at src/core/ipv6/ip6.c line 1312.
    
    [erik@kryo.se: Apply fix to ip6_output_hinted as well]
