Fix a bug where FIFO recording could not work. Example (in step by step explanation): 1. Run Dolphin. 2. Go to Tools -> Fifo Player 3. Go to the Record tab and hit record and then stop without a game loaded. The button is now disabled and will not become active again for the whole time that Dolphin is running. Dolphin must be closed and then re-opened in order to use it again. This fixes that. I've tested it with multiple conditions to make sure this doesn't beef anything else related to the Fifo Player. ie) - Record then Stop without a game loaded (multiple times) - Record then Stop with a game loaded (multiple times, as well as testing playback. All of which work fine).
