usb: gadget: uvc: Set the vb2 queue timestamp flagsuvcvideo-gadget
The vb2 queue timestamp_flags field must be set by drivers, as enforced
by a WARN_ON in vb2_queue_init. The UVC gadget driver failed to do so.
This resulted in the following warning.
[ 2.104371] g_webcam gadget: uvc_function_bind

[ 2.106779] WARNING: CPU: 0 PID: 1 at drivers/media/v4l2-core/videobuf2-core.c:2207 vb2_queue_init+0xa3/0x113()
Fix it.
