Fix segmentation fault in TRT_RodDecoder
- Ensure that the nstatus value extracted from the status data block of TRT ROB fragments is sensible. This fixes a segmentation fault caused by a corrupt ROB fragment.
- Skip data words with invalid ID hashes. Otherwise these invalid ID hashes will lead to undefined behaviour (e.g. segmentation fault).
