usb: gadget: uvc: Rename bmInterfaceFlags -> bmInterlaceFlags

Browse Source 
In the specification documents for the Uncompressed and MJPEG USB
Video Payloads, the field name is bmInterlaceFlags - it has been
misnamed within the kernel.

Although renaming the field does break the kernel's interface to
userspace it should be low-risk in this instance. The field is read
only and hardcoded to 0, so there was never any value in anyone
reading it. A search of the uvc-gadget application and all the
forks that I could find for it did not reveal any users either.

Fixes: cdda479f15 ("USB gadget: video class function driver")
