Actually new_json_obj is used in later patches 2 and 3.

Why not to use @pretty from utils.c/utils.h recently added as common
point for json_print.c and rest of the code with  commit 543365670534
("ip: Use single variable to represent -pretty")?

While new_json_obj() from json_print.c isn't used in bridge/ it is still
seems reasonable in my opinion to use common @pretty variable.
