acpi_execute_simple_method() takes a method parameter which tells it to
look for the given method underneath the given handle, so calling
acpi_get_handle() beforehand is redundant. Replace the call to
acpi_get_handle() with a call to acpi_execute_simple_method(), thus
eliminating the need for a local variable storing the handle. Also do
not assign a default value to status as it has no influence on execution
flow.
