Daniel P. Berrangé 5a1f614d0c 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.
