[27/27] media: uvcvideo: use usb_fill_int_urb()

[Sebastian Andrzej Siewior <bigeasy@linutronix.de>]

Using usb_fill_int_urb() helps to find code which initializes an
URB. A grep for members of the struct (like ->complete) reveal lots
of other things, too.
usb_fill_int_urb() also checks bInterval to be in the 1…16 range on
HS/SS.
