Revert "Make sure clk scaling happens only when HBA is runtime ACTIVE"

Commit c17cfe1caaa9 ("scsi: ufs: Make sure clk scaling happens only
when HBA is runtime ACTIVE") is no longer needed since commit
2bb5dcf38c1e ("scsi: ufs: Protect some contexts from unexpected clock
scaling") is a more mature fix to protect UFS LLD stability from clock
scaling invoked through sysfs nodes by users.
