Don't allocate way too much memory in wxVector::reserve().

We multiplied the number of items by the size of each element twice, once in
wxVector::reserve() itself and once in Ops::Realloc() it called, so we
allocated much more memory than actually needed.

Fix this by passing the number of elements to Ops::Realloc().
