acpi_has_method() is unnecessary within __query_block() and should be
removed to avoid extra work.
wc_status is initialized to AE_ERROR before the acpi_has_method() call.
acpi_has_method() and acpi_execute_simple_method() failing due to the
method not existing will result in the same outcome from __query_block().
