[CRITICAL] Fix bug that randomly disables Krita tablet support

There was an uninitialized variable that caused updateAxesData() randomly
disable Krita tablet suport. That caused the stylus to freeze randomly
until the next Leave/Enter pair.

Workaround: if you see this bug and cannot update, just restart Krita until
you don't have this behavior. If you don't have it right after the start,
then the variable was (randomly) initialized "correctly".
