Feeds: Simplify logic for checking if the `do_feed_{$feed}` action is hooked to any callbacks.
See [35097] for where the aforementioned hook was renamed to actually be dynamic, thus rendering creation of the extra `$hook` variable moot. See #34264. git-svn-id: https://develop.svn.wordpress.org/trunk@35098 602fd350-edb4-49c9-b593-d223f7449a82
