fix segfault introduced by Pierre in a recent commit

old code was doing something like
conn + sizeof(MYSQLND) * MYSQLND + plugin * sizeof(void) * sizeof(MYSQLND)
because `conn` is not casted to void*. `conn` has to be casted to void * and
then the whole experession will be void * and the calculations will work.
