Subject: [PATCH] scsi: ufs: ufshpb: Use proper power management API

In ufshpb, pm_runtime_{get,put}_sync() are used to avoid unwanted runtime
suspend during query requests. In commit b294ff3e3449 ("scsi: ufs: core:
Enable power management for wlun") has been modified to use
ufshcd_rpm_{get,put}_sync() APIs.

This patch has been modified to use these APIs in HPB module.
