    network: drop unneeded null-check for ip4 address
    
    The pointer has already been dereferenced. Might have made more sense
    to check if it's the empty string and treat that as error, but
    nm_utils_ipaddr_valid also returns error on empty string so lets just
    rely on the utility function doing the right thing here.
