Alan Stern 194d238608 USB: fix usbfs regression ...

commit 7152b592593b9d48b33f8997b1dfd6df9143f7ec upstream.

This patch (as1352) fixes a bug in the way isochronous input data is
returned to userspace for usbfs transfers.  The entire buffer must be
copied, not just the first actual_length bytes, because the individual
packets will be discontiguous if any of them are short.
