[PATCH v4 iproute2-next 05/11] tc_util: fix clang warning in print_masked_type

[Stephen Hemminger <stephen@networkplumber.org>]

Clang complains about passing a non-format string but the code here
was doing extra work the JSON case. Using print_uint_name_value here
makes the code much simpler.

Old code was also broken if using oneline mode.

Fixes: 04b215015ba8 ("tc_util: introduce a function to print JSON/non-JSON masked numbers")
