[libmicrohttpd] (GNUTLS_E_INTERRUPTED != res) checked twice

[Lasa Martxel]

Hello,

I have found the following code in daemon.c file, lines 1449 to 1467:

      if (0 >= res)
        {
          if (GNUTLS_E_INTERRUPTED != res)
            {
              urh->app.celi &= ~MHD_EPOLL_STATE_WRITE_READY;
              if (GNUTLS_E_INTERRUPTED != res)

(GNUTLS_E_INTERRUPTED != res) is checked twice.

In the read part (a few lines above), GNUTLS_E_INTERRUPTED != res is checked 
first and then GNUTLS_E_AGAIN != res. It looks like something similar should be 
done here, but I'm not sure.

Thanks,
Martxel
