Nikita Kiryushin 85c410f65b ACPICA: debugger: check status of acpi_evaluate_object() in acpi_db_walk_for_fields()
[ Upstream commit 40e2710860e57411ab57a1529c5a2748abbe8a19 ]

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.
