The wasysym docs say that there should be no conflict, but that seems
to be wrong: ISTR multiple instances of this conflict.

If you prefer the amsmath integral signs over the wasysym ones, then
probably the best thing to do is to load wasysym with the
``nointegrals'' option:

   \usepackage[nointegrals]{wasysym}

This can be done permanently by customizing
org-latex-default-packages-alist and adding the option to the wasysym
entry.
