scsi: ufs: core: Fix clk scaling to be conditional in reset and restore

[ Upstream commit 2e083cd802294693a5414e4557a183dd7e442e71 ]

In ufshcd_host_reset_and_restore(), scale up clocks only when clock
scaling is supported. Without this change CPU latency is voted for 0
(ufshcd_pm_qos_update) during resume unconditionally.
