[PATCH 4.0-testing 07/10] ACPI: acpi_table_parse() should return handler's error code

[Ian Campbell <ian.campbell@citrix.com>]

From: Boris Ostrovsky <boris.ostrovsky@amd.com>

Currently, the error code returned by acpi_table_parse()'s handler
is ignored. This patch will propagate handler's return value to
acpi_table_parse()'s caller.
