Subject: [PATCH] eth/filters: return correct JSON-RPC error code for block
 range limit

Change error from fmt.Errorf to invalidParamsErr to return proper
JSON-RPC error code (-32602 Invalid Params) instead of internal
error code (-32603 Internal Error) when block range exceeds limit.

Fixes #34646
