This change was intentional. Unfortunately, it didn't make it into the patch notes.
Dismiss Pet was frequently being used to bypass cooldowns on certain pet abilities, such as Roar of Sacrifice, or to swap out a dangerously wounded pet for one at full health. Neither of those were intended behavior. Furthermore, our design is that choosing your pet should feel similar to choosing a glyph or talent during pre-match preparation.
With this change, Hunters are able to switch pets during the pre-match preparation period, but unable to dismiss them once the match has begun.
