hw/hyperv/syndbg: skip automatic zero-init of large array

The 'handle_recv_msg' method has a 4k byte array used for copying
data between the network socket and guest memory. Skip the automatic
zero-init of this array to eliminate the performance overhead in the
I/O hot path.

The 'data_buf' array will be fully initialized when data is read
off the network socket.

hw/hyperv/balloon: Consolidate OBJECT_DEFINE_SIMPLE_TYPE_WITH_INTERFACES

The QOM type of HvBalloon is declared by OBJECT_DECLARE_SIMPLE_TYPE,
which means it doesn't need the class!

Therefore, use OBJECT_DEFINE_SIMPLE_TYPE_WITH_INTERFACES to implement
the type, then there's no need for class definition.
