Use VIR_ERR_CONFIG_UNSUPPORTED if requested security driver is disabled
Use VIR_ERR_CONFIG_UNSUPPORTED if requested security driver is disabled

security driver was disabled, from the case where no security driver
was available. Use VIR_ERR_CONFIG_UNSUPPORTED as the error when an
explicitly requested security driver was disabled
