Extraneous write to LU_ERR with ULMAT HYPRE

Decided to test a slightly different case as I was testing the bundle and found this:

Looks like you have CHECK_POISSON set to true?

[rmcdermo]

Yes. I think CHECK_POISSON and something like PRESSURE_SOLVER_VERBOSE should be independent. But too late for this release. Whatever we do needs to be documented. Let's leave this open and I'll address it later.

@gforney we do not need to hold up release over this.
