util: Fixing invalid error checking from virPCIGetNetname()

The @linkdev is In/Out function parameter as second order
reference pointer so requires first order dereference for
checking NULL which can be the result of virPCIGetNetName().

Fixes: d6ee56d7237 (util: change virPCIGetNetName() to not return error if device has no net name)
