USB: usbfs: only copy the actual data received
commit d4a4683ca054ed9917dfc9e3ff0f7ecf74ad90d6 upstream
We need to only copy the data received by the device to userspace, not
the whole kernel buffer, which can contain "stale" data.
Thanks to Marcus Meissner for pointing this out and testing the fix.
