libnvdimm: provide module_nd_driver wrapper 



Provide a module_nd_driver() wrapper over simple nd_driver_register()
nd_driver_unregister() combinations in module_init() and module_exit()
respectively.

Note an explicit nd_driver_unregister() had to be implemented as nd
bus drivers did call device_unregister() direcly in the module_exit()
function.
