ovl: Use out_err instead of out_nomem
Right now we use goto out_nomem which assumes error code is -ENOMEM. But
there are other errors returned like -ESTALE as well. So instead of
out_nomem, use out_err which will do ERR_PTR(err). That way one can put
error code in err and jump to out_err.
This just code reorganization and no change of functionality.
I am about to add more code and this organization helps laying more code
and error paths on top of it.
