hwmon: (dell-smm) Add Inspiron 3505 to fan type blacklist

Sadly, while firmware 1.5 fixed temperature labels on my
Inspiron 3505, it also caused fan type calls to take
ca. 4 seconds with the fan being at full speed.
Fix the resulting delays by adding the model to the
blacklist.

Tested on a Dell Inspiron 3505.
