Roger Quadros 5c836e4d58 usb gadget: composite: prevent OOPS for non-standard control request 
The composite gadget will OOPS if the host sends a control request
targetted to an interface of an un-configured composite device. This patch
prevents this.

The OOPS was observed during WHQL USB CV tests. With this patch, the device
STALLs as per requirement.

Failing test case: From host do the following. I used libusb-1.0

1) Set configuration to zero.
	libusb_control_transfer(device_handle,
		0, /* standard OUT */
		0x9, /* setConfiguration */
		0, 0, NULL, 0, 0);

2) Query current configuratioan.
	libusb_control_transfer(device_handle,
		0x80, /* standard IN*/
		0x8, /* getConfiguration */
		0, 0, data, 1, 0);

3) Send the non-standard ctrl transfer targetted to interface
	libusb_control_transfer(device_handle,
		0x81, /* standard IN to interface*/
		0x6, /* getDescriptor */
		0x2300, 0, data, 0x12, 0);
