thermal: trip: Drop redundant trips check from for_each_thermal_trip()
[ Upstream commit a15ffa783ea4210877886c59566a0d20f6b2bc09 ]
It is invalid to call for_each_thermal_trip() on an unregistered thermal
zone anyway, and as per thermal_zone_device_register_with_trips(), the
trips[] table must be present if num_trips is greater than zero for the
given thermal zone.
Hence, the trips check in for_each_thermal_trip() is redundant and so it
can be dropped.
