mm: change type of parameter for memory_notify
memory_notify() is responsible for sending events related to memory
hotplugging to a notification queue. Since all the events must match one
of the values from the enum memory_block_state, it is appropriate to
change the function parameter type to make this condition explicit at
compile time.
