[PATCH v2 1/6] platform/x86: dell-smo8800: Change probe() ordering a bit

[Hans de Goede <hdegoede@redhat.com>]

Retrieve the IRQ number from the platform_device a bit earlier
and only call platform_set_drvdata() on successful probe
(the drvdata is only used from the remove() callback).

This is a preparation patch for moving the lis3lv02d i2c_client
instantiation from the i2c-i801 driver to dell-smo8800.
