Subject: [PATCH iproute2] u32: fix TC_U32_TERMINAL printing

We previously printed an asterisk if there was no 'sel' or 'TC_U32_TERMINAL'
flag. However, commit 1ff22754 ("u32: fix json formatting of flowid")
changed the logic to print an asterisk only if there is a 'TC_U32_TERMINAL'
flag. Therefore, we need to fix this regression.

Fixes: 1ff227545ce1 ("u32: fix json formatting of flowid")
