efi_loader: non-volatile variable not deleted from file
When deleting a non-volatile variable it was deleted from memory but the deletion was not persisted to the file system. SetVariable() may be called with attributes == 0 to delete a variable. To determine if the deletion shall be persisted we have to consider the non-volatile flag in the attributes of the deleted variable and not the value passed in the call parameter.
