platform/x86: wmi: move dev_to_wblock() and dev_to_wdev to use container_of_const()

Browse Source 
The driver core is changing to pass some pointers as const, so move the
dev_to_wdev() and dev_to_wblock() functions to use container_of_const()
to handle this change.

Both of these functions now properly keep the const-ness of the pointer
passed into it, while as before it could be lost.
