The row-major branches of cherk/zherk and cher2k/zher2k mapped the invalid CblasTrans to 'N', and those of csyrk/zsyrk and csyr2k/zsyr2k mapped the invalid CblasConjTrans to 'N', silently computing a different operation instead of rejecting the argument. The column-major branches forward these values to the Fortran routine, which reports them as an illegal second argument (parameter 3 of the CBLAS call). Drop the bogus mappings so the invalid values reach the row-major branches' existing error exits, which also report parameter 3. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
