[PATCH iproute2-next] ipioam6: use print_nl instead of print_null

[Justin Iurman <justin.iurman@uliege.be>]

This patch addresses Stephen's comment:

"""
> +        print_null(PRINT_ANY, "", "\n", NULL);

Use print_nl() since it handles the case of oneline output.
Plus in JSON the newline is meaningless.
"""

It also removes two useless print_null's.
