Remove shadowed duplicate definitions (F811)

Three names were defined twice in the same scope, so the first definition
was unreachable:

- lenovo OEM handler: two set_user_access methods, the second silently
  replacing the first.  That made the SMM privilege update dead code.  The
  conditions are mutually exclusive (is_fpc returns None once has_xcc is
  true), so merge both into the surviving method.
- redfish plugin handle_cert_authorities and prepfish
  disable_host_interface: byte identical copies, drop the redundant one.
