[ion] 21934: - Use EPROCESS 's AddressCreationLock instead of the MADDRESS_SPACE Lock. - Overlay MADDRES_SPACE over MM_AVL_NODE. Even though our structures are currently incompatible, they represent the same thing (The EPROCESS's Address space).

Log:
- Use EPROCESS 's AddressCreationLock instead of the MADDRESS_SPACE Lock.
- Overlay MADDRES_SPACE over MM_AVL_NODE. Even though our structures are currently incompatible, they represent the same thing (The EPROCESS's Address space).
