scsi: ufs: fail ufshcd_probe_hba() if power configuration fails

In case the power configuration fails, skip further processing
of the  probing function and return immediately. This has 2 reasons:
1. Don't allow the UFS to continue running in PWM
2. Avoid multiple calls to pm_runtime_put_sync() when not
   in error handling or power management contexts
