[PATCH] USB: bug fix in usbdevfs 

I am sorry that the last patch about 32 bit compat ioctl on
64 bit kernel actually breaks the usbdevfs. That is on the current
BK tree. I am retarded. 

Here is the patch to fix it. Tested with USB hard disk and webcam
in both 32bit compatible mode and native 64bit mode.

Again, sorry about that.
