Fix warnings: tag.c: get_tags(): Uninitialized arg: RI.

Problem    : Uninitialized argument value @ 2798.
Diagnostic : Real issue.
Rationale  : Tags doesn't have to have a kind. When they have one, both
             `tp.tagkind` and `tp.tagkind_end` are nonnull. But when
             they don't, `tp.tagkind` will we null (but defined), while
             `tp.tagkind_end` will be undefined.
             Therefore, reported invocation is indeed using a garbage
             value for a tag with no kind.
             Problem doesn't have consequences because `add_tag_field()`
             doesn't use `end` param if `start` param is null.
Resolution : Don't use `tp.tagkind_end` if `tp.tagkind` is null.
