Disallow initalization of unknown device axis by wcmInitAxis
Addresses the following compile warning from GCC:
../src/x11/xf86Wacom.c: In function ‘wcmInitAxis’:
../src/x11/xf86Wacom.c:538:9: warning: ‘index’ may be used
uninitialized in this function [-Wmaybe-uninitialized]
Attempting to initialize an unknown axis will now result in a program
abort. This copies the behavior used by the `convertAxes` function.
