cblas_ctrmm invalid diag problem

Hi Devin,

In https://github.com/flame/blis/blob/master/frame/compat/cblas/src/cblas_ctrmm.c, for the layout CblasColMajor case (line ~76) the code is missing the

     CBLAS_CallFromC = 0;
     RowMajorStrg = 0;
     return;

statements present in other error checks in this file and other trmm variants. This problem comes from the Netlib version, I've raised an issue there too.

Thanks,
Ed
