i2c_acpi_new_device() never returns NULL, it either returns an i2c_client
or a PTR_ERR. Adjust the mshw0011_probe() error handling to take this
into account.
Note the goto out_err will cause i2c_unregister_device() to get called
even though the i2c_acpi_new_device() fails, this is ok as it accepts
a NULL pointer argument (and treats it as a no-op).
