scsi: ufs: Avoid NULL CQE dereference when reporting invalid tags

Browse source

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.
