Remove unnecessary user retrieval in v2raysocks (XrayR-project#617)

The updated code eliminates a redundant user retrieval operation in the v2raysocks module. This operation was not needed because the desired information (method) can be inferred elsewhere in the application. This change simplifies the code, improves efficiency, and may reduce potential errors related to user data retrieval.
