refactor(rpc): initial zero check in create_node

The caller (`graph_compute`) already checks `id != 0` when handling
a `nullptr` return from `create_node`, correctly distinguishing
intentional null links from actual errors. This makes the initial
`if (id == 0)` check redundant.

Also removes the log message when a tensor ID is not found in the
provided map which was added in this branch.
