This hack is only needed for Huion tablets. It does not seem to have
any effect on the other tablets handled by this device right now, but
it's better to check for the product id sooner than discovering that
we have messed up one tablet later.

changes in v3:
- stores a flag to know when to invert the bit.

It would be nice to also use this macro in the replaced report descriptor
itself, but this will do for now.

Thanks a lot, Benjamin!

P.S. I like the way you describe the changes between patchset versions, will
have to keep it in mind and use in my own.
