PM / QoS: Fix the return value of dev_pm_qos_update_request()
Commit e39473d (PM / QoS: Make it possible to expose PM QoS device
flags to user space) introduced __dev_pm_qos_update_request() to be
called internally by dev_pm_qos_update_request(), but forgot to make
the latter actually use the return value of the former. Fix this
mistake.
