Pegasus driver used single callback for sync and async control URBs. Special flags were employed to distinguish between both, but due to flawed logic it didn't always work. As a result of this change [get|set]_registers() are now much simpler. Async write is also leaner and does not use single, statically allocated memory for usb_ctrlrequest, which is another potential race when asynchronously submitting URBs.
