hwmon: (ntc_thermistor) Ensure that data->name string is terminated

Browse Source 
Fix Coverity warning: Calling strncpy with a maximum size argument of 20 bytes
on destination array "data->name" of size 20 bytes might leave the destination
string unterminated.

Fix by replacing strncpy() with strlcpy() and by using sizeof() to determine
the maximum string length.
