Input: psmouse - fix breakage introduced by b7802c5c1ea

Commit b7802c5c1ea ("Input: psmouse - use boolean type") caused the
synaptics_hardware variable to be completely useless, as it is
constantly set to 'true' throughout the whole psmouse_extensions().
This was caused by the following hunk in the commit in question

	-       int synaptics_hardware = 0;
	+       bool synaptics_hardware = true;

which is wrong and causes driver to issue extra reset when falling
back to bare PS/2 protocol.
