scsi: ufs: core: Fix another deadlock during RTC update

commit cb7e509 upstream.

If ufshcd_rtc_work calls ufshcd_rpm_put_sync() and the pm's usage_count
is 0, we will enter the runtime suspend callback.  However, the runtime
suspend callback will wait to flush ufshcd_rtc_work, causing a deadlock.

Replace ufshcd_rpm_put_sync() with ufshcd_rpm_put() to avoid the
deadlock.
