Since isochronous transfers cannot be handled async (the function
returns error in that case) we don't need to remember the packet.
Avoid using the usb_packet field in OHCIState (as that can be a
waiting async packet on another endpoint) and allocate and use a local
USBPacket for the iso transfer instead. After this we don't have to
care if we're called from a completion callback or not so we can drop
that parameter as well.
