r8152: fix the list rx_done may be used without initialization

The list rx_done would be initialized when the linking on occurs.
Therefore, if a napi is scheduled without any linking on before,
the following kernel panic would happen.

BUG: unable to handle kernel NULL pointer dereference at 000000000000008
