Input: synaptics - fix wrong dimensions check
The commit 83ba9ea8a04b72dfee2515428c15e7414ba4fc61 ommitted the return line for the old synaptics model accidentally. This resulted in a wrong check, namely, the dimensions are checked for the old devices that don't support the query properly. This patch adds the return line back.
