ufs: core: fix another deadlock when rtc update

From: Peter Wang <[email protected]>

When ufshcd_rtc_work calls ufshcd_rpm_put_sync and the pm's usage_count is 0, it will enter the runtime suspend callback. However, the runtime suspend callback will wait to flush ufshcd_rtc_work, causing a deadlock.
Replacing ufshcd_rpm_put_sync with ufshcd_rpm_put can avoid the deadlock.
