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.

major and minor numbers")
