scsi: ufs-qcom: fix symbol clocks handling

Browse source 
We are only enabling the lane-0 symbol clock in 1-lane configuration
but it seems during disabling we are trying to disable lane-1 symbol
clocks as well even if they were never enable in 1-lane configuration,
this change fixes this minor issue.
