This patch fixes newly introduced sparse warning in
ufshcd_system_suspend, introduced by UFS power management series.
Sparse warning:
drivers/scsi/ufs/ufshcd.c:5118 ufshcd_system_suspend()
error: we previously assumed 'hba' could be null (see line 5089)
To fix it, we return 0 in case HBA is not initialized or is
not powered.
