Describe the contribution

• Fixes Multiple return statements in LC_CreateTaskCDS and LC_TableInit #36 (partially - will separate out LC_CreateTaskCDS() into a new issue to tackle separately).
  • Multiple returns have been removed from LC_TableInit().
  • There is now a single exit from the function.

Testing performed
GitHub CI Build + Run, Unit Tests all passing successfully.

Expected behavior changes
Essentially no change to logic.
Previous early return exit points will now fail all the following tests for if (Result == CFE_SUCCESS) and fall through to the end of the function, where Result is returned.
