When building s390 allmodconfig after commit 9b91a65230 ("usb: gadget:
uvc: increase worker prio to WQ_HIGHPRI"), the following error occurs:

This points to the memset() in uvc_register_video(). It is clear that
the argument to sizeof() is incorrect, as uvc->vdev (a 'struct
video_device') is being zeroed out but the size of uvc->video (a 'struct
uvc_video') is being used as the third arugment to memset().
pahole shows that prior to commit 9b91a65230 ("usb: gadget: uvc:
increase worker prio to WQ_HIGHPRI"), 'struct video_device' and
'struct ucv_video' had the same size, meaning that the argument to
sizeof() is incorrect semantically but there is no visible issue:
$ pahole -s build/drivers/usb/gadget/function/f_uvc.o | grep -E "(uvc_video|video_device)\s+"
video_device 1400 4
uvc_video 1400 3
After that change, uvc_video becomes slightly larger, meaning that the
memset() will overwrite by 8 bytes:
$ pahole -s build/drivers/usb/gadget/function/f_uvc.o | grep -E "(uvc_video|video_device)\s+"
video_device 1400 4
uvc_video 1408 3
Fix the arugment to sizeof() so that there is no overwrite.

This patch is changing the simple workqueue in the gadget driver to be
allocated as async_wq with a higher priority. The pump worker, that is
filling the usb requests, will have a higher priority and will not be
scheduled away so often while the video stream is handled. This will
lead to fewer streaming underruns.
