usb: gadget: f_uvc: Fix SuperSpeed companion descriptor's wBytesPerInterval
commit 09424c50b7dff40cb30011c09114404a4656e023 upstream.
The streaming_maxburst module parameter is 0 offset (0..15)
so we must add 1 while using it for wBytesPerInterval
calculation for the SuperSpeed companion descriptor.
Without this host uvcvideo driver will always see the wrong
wBytesPerInterval for SuperSpeed uvc gadget and may not find
a suitable video interface endpoint.
e.g. for streaming_maxburst = 0 case it will always
fail as wBytePerInterval was evaluating to 0.
