scsi: ufs: Skip last hci reset to get valid register values

Once the host link startup fails 3 times, all host registers are reset to
default values except in ufshcd_hba_enable().

The ufs host controller is disabled and enabled in ufshcd_hba_enable().
Consequently we need to skip last hci reset to get valid host register
values.
