Coding Standards: Remove duplicate assignment from a ternary operator in `WP_MS_Sites_List_Table::site_states()`.

Adjust similar code in `_post_states()` and `_media_states()` for consistency.

Follow-up to:
* [12897], [15491], [32755], [46153], [48424] for `WP_MS_Sites_List_Table::site_states()`.
* [17793], [47775], [49223] for `_media_states()`.
* [9153], [46309] for `_post_states()`.
