Fan: Optimize the pwm sensor creation

Given fan*_input and its corresponding pwm* hwmon sys files are always
under the same diretory, we should use that directory to generate the
pwm sensor rather than deduce it from scratch. This also fixes all
kind of issues that come into play when multiple fan hwmon controllers
exisit on the system.

Tested: the tach and pwm sensors continue to be the same as before.
