…blem (NVIDIA#477) Fix an issue where the free variable info from the original problem was being used on the folded problem. This was leading to undefined memory access. Thanks to Burcin for reporting the bug and Hugo for determining the issue.

Minor tweaks to the barrier log. Authors: - Chris Maes (https://github.com/chris-maes) Approvers: - Hugo Linsenmaier (https://github.com/hlinsen) URL: NVIDIA#478
This PR also fixes the starting bounds for the diving subtrees. As these nodes are detached from the main B&B tree, the bounds from the parent were lost. Now, the bounds are also kept when inserting the nodes in the diving queue. Authors: - Nicolas L.

CUDSS does not throw on OOM and even though we check for the return status. There was a sticky cuda error on any successive CUDA API call. A workaround is to throw if `cudaMallocAsync` fails in the device mem handler and catch that error in the solve method.

…VIDIA#484) @tmckayus reported that in concurrent mode, he was seeing lots of barrier numerical status. This was due to incorrectly setting the status to NUMERIC, when barrier was stopped by PDLP or concurrent. This PR fixes the issue, by checking for concurrent limit first. Logs are also changed for consistency. Authors: - Chris Maes (https://github.com/chris-maes) Approvers: - Hugo Linsenmaier (https://github.com/hlinsen) URL: NVIDIA#484
