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
