Subject: [PATCH 8/8] staging: vchiq_core: Lower indentation in vchiq_close_service_internal

Reduce indentation of the conditional nesting in
vchiq_close_service_internal() switch case by checking the error paths
first and break early. This helps to reduce conditional branching and
reduce indentation levels.
