SnpDxe registers for an ExitBootServices callback and runs the PXE_OPCODE_SHUTDOWN and PXE_OPCODE_STOP commands for any network controllers that the driver is attached to. Register the SnpDxe callback for gEfiEventBeforeExitBootServicesGuid instead of gEfiEventExitBootServicesGuid to ensure the correct ordering: 1. ExitBootServices event 2. Network card shutdown sequence is completed Also, close the event to prevent rerunning the shutdown if multiple ExitBootServices events need to be called by the OS.
