media: rcar-vin: fix wrong return value in rvin_set_channel_routing()

Browse Source 
If the operation in rvin_set_channel_routing() is successful the 'ret'
variable contains the runtime PM use count for the VIN master device.
The intention is not to return the use count to the caller but to return
0 on success else none zero.

Fix this by always returning 0 if the operation is successful.
