staging: usbip: bugfix add number of packets for isochronous frames
commit 1325f85fa49f57df034869de430f7c302ae23109 upstream. The number_of_packets was not transmitted for RET_SUBMIT packets. The linux client used the stored number_of_packet from the submitted request. The windows userland client does not do this however and needs to know the number_of_packets to determine the size of the transmission.
