Subject: [PATCH v3 1/2] thermal: trip: Drop a redundant check from thermal_zone_set_trip()

After recent changes in the thermal framework, a trip points array is
required for registering a thermal zone that is not tripless, so the
tz->trips pointer in thermal_zone_set_trip() is never NULL and the
check involving it is redundant.  Drop that check.

No functional impact.
