ACPICA: debugger: check status of acpi_evaluate_object() in acpi_db_walk_for_fields()
ACPICA commit 9061cd9aa131205657c811a52a9f8325a040c6c9
Errors in acpi_evaluate_object() can lead to incorrect state of buffer.
This can lead to access to data in previously ACPI_FREEd buffer and
secondary ACPI_FREE to the same buffer later.
Handle errors in acpi_evaluate_object the same way it is done earlier
with acpi_ns_handle_to_pathname.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
