efi_loader: run CreateEvent() notify function based on flags
The UEFI specification states that the tpl, function and context
arguments are to be ignored if neither EVT_NOTIFY_WAIT or
EVT_NOTIFY_SIGNAL are specified. This matches observed behaviour with
an AMI EDK2 based UEFI implementation.
Skip calling the notify function if neither flag is present.
