[PATCH] ATMEL USB: pass unknown FEATURE SET requests to gadget

When using the dbgp gadget with the atmel usb controller, the following
message is logged:

udc: ep0: Invalid setup request: 00.03 v0006 i0000 l0, halting endpoint...

That makes the gadget unusable with the atmel usba controller driver. Fix this
by passing unknown request to the gadget driver.
