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.

Fixes: 969890d505b1 ("net/ice/base: enable clearing of HW tables")
