    Always check whether netif_default is NULL
    
    In general, netif_default may be NULL, and various places in the code
    already check for this case before attempting to dereference the
    netif_default pointer.  Some places do not perform this check though,
    and may cause null pointer dereferences if netif_default is not set.
    This patch adds NULL checks to those places as well.
