PM QoS: Minor clean-ups

 - Misc fixes to improve code readability:
  * rename struct pm_qos_request_list to struct pm_qos_request,
  * rename pm_qos_req parameter to req in internal code,
    consistenly use req in the API parameters,
  * update the in-kernel API callers to the new parameters names,
  * rename of fields names (requests, list, node, constraints)
