Commit <52a518019c> ("Fix missing clk change notification on host reset")
added clock scaling notification to ufshcd_host_reset_and_restore.
This invokes hibern8 enter and exit on qualcomm platform which fails
because controller is in reset state.
Fix this by checking the Host controller state before sending
hibern8 command.
