Fix value passed to SPEED in air-filteration.md macro. (#3133)

Fix value passed to SPEED The SPEED parameter of SET_FAN_SPEED needs to be between 0.0 and 1.0. Since the S param, which is between 0 and 255, was being passed as is to SPEED, it effectively resulted in the target fan running at 100% if any value > 0 was passed to M106.
