hyperref uses "\theHfigure" for building the
destination name for figures. So you can locally
rename the value it for the second figure with
the same number:

\begin{figure}
  \caption{hello}
\end{figure}
\addtocounter{figure}{-1}
\begin{figure}
  \renewcommand{\theHfigure}{cont.\arabic{figure}}%
\end{figure}

PS: If you want to avoid the extra vertical space,
    introduced by the center environment, you can
    use \centering instead.
