 platform/wmi: Fix unchecked min_size in wmidev_invoke_method() 
After calling wmidev_evaluate_method(), if the ACPI core does not return
an out object, then wmidev_invoke_method() bypasses the min_size check
and returns 0. Add a check for min_size if there is not an out object.

Fixes: 1aeded2f55 ("platform/wmi: Extend wmidev_query_block() to reject undersized data")
Closes: https://sashiko.dev/#/patchset/20260406203237.2970-1-W_Armin%40gmx.de
