scsi: ufs: Avoid NULL CQE dereference when reporting invalid tags
The single-doorbell completion path can call ufshcd_compl_one_cqe() with a NULL CQE. If no command is associated with the completion tag, the warning message dereferences the CQE while reporting the error. Avoid that dereference and include the invalid tag in the warning.
