tsl1401cl_filament_width_sensor: Fix incorrect math in filament width sensor. (#1541)
The parameter to the M221 command should be the ratio of the nominal to
measured filament area, rather than the ratio of the diameters. Since we
are taking the ratio, most of the area calculation cancels out.
Fixes #1535.
