Ordering mistake in the DEVICE_WRITE_CALL struct in Vxi11.cs

[DEddyDave]

The flag variable must be behind the io_timeout and lock_timeout.

public struct DEVICE_WRITE_CALL
        {
            public int xid;
            public int msg_type;
            public int rpcvers;
            public int prog;
            public int vers;
            public int proc;
            public int cred_flavor;
            public int cred_len;
            public int verf_flavor;
            public int verf_len;
            public int lid;
            
            public int io_timeout;
            public int lock_timeout;
            public int flags;

            public int data_len;
        };
