[ Upstream commit ec1d1d2302067e3ccbc4d0adcd36d72410933b70 ]
This fix has been added to address memory leak issues resulting from triggering a sudden driver reset which does not allow us to follow our normal removal flows for SW XLT entries for advanced features.
- Adding call to destroy flow profile locks when clearing SW XLT tables.
- Extraction sequence entries were not correctly cleared previously which could cause ownership conflicts for repeated reset-replay calls.
