    req: Don't reserve space for htc twice
    
    When struct req changed to no longer store its htc, which was somewhat
    hidden in a larger seemingly unrelated change, it ended up being
    reserved twice. This looks like a case of starting something, being
    interrupted, and starting again.
    
    I decided to remove the one sitting between the reservation of VDP and
    VFP contexts since the two are related, and this reservation didn't even
    initialize htc.
