xpp: Use proper get/set for device->driver_data

2.6.32-rc1 broke direct access to the member 'driver_data' of 'struct
device'. However direct access to wasn't proper in the first place.

This commit replaces direct access to dev->driver_data with
dev_get_drvdata() and dev_set_drvdata().

This is a backport from https://origsvn.digium.com/svn/dahdi/linux/trunk@7226.
