[PATCH] nv: Fix variable removal in nvvar_save()

[Sascha Hauer]

When nv variables are removed during runtime then they are
present again when saved with nvvar_save(). This is because nvvar_save()
does not delete variables that exist on the saved environment. Delete
/nv on the saved environment before saving the new variables.
