acknowledge() and acknowledge_failed_transfer_trbs() call trb.reserved(false) (a &mut self method) on a by-value `trb: Trb` parameter that wasn't declared mut. Bind it `mut trb: Trb` (the parameter is owned, so this is sufficient). Fixes the 2 E0596 errors that failed `cook base`; the 49 warnings are non-fatal.
