USB: usbdevfs: sanitize flags more
commit 7a68d9fb851012829c29e770621905529bd9490b upstream.
Requesting a ZERO_PACKET or not is sensible only for output.
In the input direction the device decides.
Likewise accepting short packets makes sense only for input.
This allows operation with panic_on_warn without opening up
a local DOS.
