hwmon: (dell-smm) Move error message to make probing silent

If dell-smm-hwmon loads on unsupported hardware like the
Dell XPS 17 9710, an error message is printed.
This might confuse users, as drivers are expected to be
silent if no supported hardware is found.
Reorder the error message so its only printed when the
driver is loaded with the "force" option being set.
Also reword the error message slightly.

Tested on a Dell Inspiron 3505.
