[PATCH V2] app/testpmd: fix display types failure when query RSS rule

[Huisong Li <lihuisong@huawei.com>]

Now testpmd fails to display types when query RSS rule. The failure is
because the '\n' character is missing at the end of the function
'rss_config_display()'. Actually, all places calling 'xxx_types_display()'
need to '\n'. So this patch moves '\n' to the inside of these function.

Fixes: 534988c490f1 ("app/testpmd: unify RSS types display")
Fixes: 44a37f3cffe0 ("app/testpmd: compact RSS types output")

v2:
 - move '\n' to the inside of 'xxx_types_display()'.
