Fix a segfault bug by asking for variable it doesn't find. Since the convert_variable() didn't handle error code returned from convert_variable_location(), it just passed an incomplete variable field and then a segfault was occurred when formatting the field. This fixes that bug by handling success code correctly in convert_variable(). Other callers of convert_variable_location() are correctly checking the return code. This bug was introduced by following commit. But another hidden erroneous error handling has been there previously (-ENOMEM case). commit 3d918a12Signed-off-by:
