Fix for ssh_channel_request_pty_size for SSH1

[Dmitriy Kuznetsov <dk@xxxxxxxxx>]

Look at the code in channels.c (master branch):
---
int ssh_channel_request_pty_size(ssh_channel channel, const char *terminal,
    int col, int row) {
  ssh_session session = channel->session;
  ssh_string term = NULL;
  ssh_buffer buffer = NULL;
  int rc = SSH_ERROR;         // <-- Init rc

  if(channel == NULL) {
      return SSH_ERROR;
  }
  if(terminal == NULL) {
      ssh_set_error_invalid(channel->session);
      return rc;
  }

  enter_function();
#ifdef WITH_SSH1
  if (channel->version==1) {
    channel_request_pty_size1(channel,terminal, col, row);
    leave_function();
    return rc;               // <-- return invalid rc, previous line
MUST be "rc = channel_request_pty_size1(channel,terminal, col, row);"
    }
#endif
