I don't believe that's possible, you can't enable zswap for only
specific swap devices; and anyway, if you fill up zram, you won't
really have any memory left for zswap to use will you?
However, it shouldn't encounter any BUG(), like you saw. If it's
reproducable for you, can you give details on how to reproduce it?
