You need to have the udev rule or the script that it runs look at
something specific(the swaplabel for instance).

I tried doing exactly what you're doing now awhile ago and this is where
I got stuck, swapoff needs the deivce node(path) to still exist, it
can't disable swap without it. I could never get swapoff to run before
udev removed the device node, so I ended up with the system thinking(or
at least reporting) that it had loads more swap than it actually did.
