Niklas Söderlund 30334d3d99 media: rcar-vin: Add check for completed capture before completing buffer ...

Before reading which slot was captured to by examining the module status
(VnMS) register, make sure something was captured at all by examining
the interrupt status register (VnINTS).

Failing this a buffer maybe completed before it was captured too.
