CHROMIUM: Input: synaptics - skip trackpoint reconnect

CHROMIUM: Input: synaptics - skip trackpoint reconnect

Since trackpoint properties are probed in the boot time, it should
be safe to skip the reconnect function as we don't need to
probe the properties again to reduce the latency of unresponsiveness.

BUG=chrome-os-partner:15015
TEST=on device; use powerd_suspend and then hit a key to wake it up
   see if the trackpoint/trackpoint could be active in 3~4 seconds
   after resume instead of 7 seconds long
