usb-storage: tag usb_msd_csw as packed struct
Without this the struct has the wrong size: sizeof() evaluates
to 16 instead of 13. In most cases the bug is hidden by the
fact that guests submits a buffer which is exactly 13 bytes
long, so the padding added by the compiler is simply ignored.
But sometimes guests submit a larger buffer and expect a short
transfer, which does not work properly with the wrong struct
size.
