hwmon: (dell-smm) Add XPS 15 L502X to fan control blacklist
It has been reported[0] that the Dell XPS 15 L502X exhibits similar freezing behavior to the other systems[1] on this blacklist. The issue was exposed by a prior change of mine to automatically load dell_smm_hwmon on a wider set of XPS models. To fix the regression, add this model to the blacklist.
