Yuan Can 5209d1b654 powercap: dtpm_devfreq: Fix error check against dev_pm_qos_add_request()

The caller of the function dev_pm_qos_add_request() checks again a non
zero value but dev_pm_qos_add_request() can return '1' if the request
already exists. Therefore, the setup function fails while the QoS
request actually did not failed.

Fix that by changing the check against a negative value like all the
other callers of the function.
