drivers/acpi/scan.c: inconsequent NULL handling

The Coverity checker found the following:

<-- snip -->

static int
acpi_bus_match (
struct acpi_device *device,
struct acpi_driver *driver)
{
if (driver && driver->ops.match)
return driver->ops.match(device, driver);
return acpi_match_ids(device, driver->ids);
}

<-- snip -->

Either driver can be NULL, in which case the driver->ids is a possible
NULL pointer reference, or it can't, in which case the check whether
it's NULL is superfluous.
