acpi_ut_create_internal_object may allocate memory from a slab cache
via kmem_cache_zalloc, but the code currently frees it with ACPI_FREE,
which calls kfree. This mismatch prevents the object from being
released properly and may lead to memory leaks or other issues.
Fix this by replacing ACPI_FREE with acpi_ut_delete_object_desc, which
matches the allocation method used for internal objects.
