get_post_format() generates queries on unsupported post types

[nacin]

get_post_format() is used in two places in the list table templating, which will cause an unnecessary term fetch query for every post. That's no fun.

I started to fix this by patching the problem instances. But it should itself bail early if the post type isn't supported. Incoming patch does both. Pick and choose.

Going with the get_post_format early return per IRC.

(In [17429]) Don't query the post format for post types that don't support formats. Props nacin. fixes #16503 for trunk
