drivers/acpi/sbs.c:acpi_sbs_remove() inconsistent NULL checking

[Adrian Bunk <bunk@stusta.de>]

The Coverity checker spotted the following inconsistent NULL checking 
introduced by commit 3f86b83243d59bb50caf5938d284d22e10d082a4:

<--  snip  -->

...
int acpi_sbs_remove(struct acpi_device *device, int type)
{
        struct acpi_sbs *sbs = (struct acpi_sbs *)acpi_driver_data(device);
        int id;

        if (!device || !sbs) {
                return -EINVAL;
        }
...

<--  snip  -->

The NULL check for "device" is three lines after it got dereferenced the 
first time.

       There are three kinds of lies: Lies, Damn Lies, and Statistics.
