usb: gadget: uvc: Remove non-required locking from 'uvc_queue_next_buffer' routine
This patch removes the non-required spinlock acquire/release calls on 'queue->irqlock' from 'uvc_queue_next_buffer' routine. This routine is called from 'video->encode' function (which translates to either 'uvc_video_encode_bulk' or 'uvc_video_encode_isoc') in 'uvc_video.c'. As, the 'video->encode' routines are called with 'queue->irqlock' already held, so acquiring a 'queue->irqlock' again in 'uvc_queue_next_buffer' routine causes a spin lock recursion.
