Binbin Zhou 15ef92e9c4 drivers/thermal/loongson2_thermal: Fix incorrect PTR_ERR() judgment 
PTR_ERR() returns -ENODEV when thermal-zones are undefined, and we need
-ENODEV as the right value for comparison.

Otherwise, tz->type is NULL when thermal-zones is undefined, resulting
in the following error:
