Daniel P. Berrangé 837b87c4c5 net/stream: skip automatic zero-init of large array ...

The 'net_stream_send' method has a 68k byte array used for copying
data between guest and host. Skip the automatic zero-init of this
array to eliminate the performance overhead in the I/O hot path.

The 'buf1' array will be fully initialized when reading data off
the network socket.
