Nitin Rawat 21f04fb4e8 scsi: ufs: ufs-qcom: Check host controller state
Commit 52a518019c ("scsi: ufs: core: Fix missing clk change notification
on host reset") added UFS 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.

__ufshcd_wl_resume()
ufshcd_reset_and_restore()
ufshcd_host_reset_and_restore()
ufshcd_scale_clks()
ufshcd_vops_clk_scale_notify()
ufs_qcom_clk_scale_notify()
ufshcd_uic_hibern8_enter()
