[PATCH] synaptics: Remove unused struct member variable

This patch removes an unused variable in the synaptics_data struct and deletes
a no longer helpful comment.  I don't think this has been used since the very
first synaptics kernel patch I submitted that did all processing in kernel
space instead of delegating most of it to the X server.
