In my efforts to work around this kernel panic, I am trying to work

call gets a failure (ie -1) returned.
The '-1' is the error indicator. The system gives you 'errno' to tell
you what went wrong. Without that information, we'd just be
speculating, without a net (as it were).
#define EINVAL 22 /* Invalid argument */
You should not be specifying a demux spec (the val and the val size
should be zero). Deleting a demux spec is an "all or nothing" deal, in
the current implementation.
The other reason for getting EINVAL is that your "control block" does
not have a DLIL tag specified.
Hope that helps.

Justin
