From: Peter Wang <peter.wang@xxxxxxxxxxxx>
After ufshcd_wl_shutdown set device power off and link off,
ufshcd_shutdown could turn off clock/power.
Also remove pm_runtime_get_sync.
The reason why here can remove pm_runtime_get_sync is because,
(1) ufshcd_wl_shutdown -> pm_runtime_get_sync, will resume hba->dev too.
(2) device resume(turn on clk/power) is not required, even if device is in RPM_SUSPENDED.
Fixes: b294ff3e3449 ("scsi: ufs: core: Enable power management for wlun")
