[PATCH 1/1] efi_loader: non-volatile variable not deleted from file

[Heinrich Schuchardt]

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.
