libcamera: media_device: Initialise local variable
The local variable ifaceId generates a compiler warning that it is used without initialisation. The loop, and check against the loop iterator, and the topology.num_interfaces actually ensures that this isn't the case, and that ifaceId can only be used when set to a valid ID. The media_v2_interface.id field documents the ID as simply "Unique ID for the interface" but does not specify if zero is a valid ID or not. As such we don't further check the pre-initialised ID for validity and keep the existing check on the iterator count to determine if the ID had been discovered successfully.
