Deadlock in `gesvx` when FACT='E'

[tlcfem]

There is a bug in the upstream project that under rare cases, `gesvx` will hang when equilibration is required.

The details of the bug and the analysis can be seen in the following issue.

https://github.com/Reference-ScaLAPACK/scalapack/issues/119

I've also provided a reference fix as shown here.

https://github.com/Reference-ScaLAPACK/scalapack/pull/120

The bug can also be reproduced in MKL.

Given that ScaLAPACK has a long release cycle, I am writing here to see if it can be fixed in MKL soonish.
