Move completed transfer descriptors to the freelist before calling
usb_transfer_complete, so that if we need to allocate a new one (as in the
case of interrupt endpoints) we will always be able to do so without
allocating a new chunk. Mapping a new chunk involves allocating from the
kernel map, which is not safe to do from interrupt context.
fixes a panic reported by semarie
