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

In the Linux kernel, the following vulnerability has been resolved:

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

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.
