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. Signed-off-by: Daniel P.
