[PATCH] ALPS: fix enabling hardware tapping

It looks like logic for enabling hardware tapping in ALPS driver was
inverted and we enable it only if it was already enabled by BIOS or
firmware.

I have a confirmation from one user that the patch below fixes the problem
for him and it might be beneficial if we could get it into 2.6.12.
