driver core: class: mark class_release() as taking a const *

Browse Source 
The struct class callback, class_release(), is only called in 2 places,
the pcmcia cardservices code, and in the class driver core code.  Both
places it is safe to mark the structure as a const *, to allow us to
in the future mark all struct class usages as constant and move into
read-only memory.
