Fix based on Coverity and Sonar audits (part 2) by stelfrag · Pull Request #22330 · netdata/netdata · GitHub

Summary

Split based on Misc fixes from Coverity and Sonar audits (cleanup batch) #22299

…NG branch Sonar c:S935 (CRITICAL): aws_kinesis_connector_worker() is declared void *, but the conditional test-only early exit inside #ifdef UNIT_TESTING used a bare `return;`. Per C99/C11 6.8.6.4, a return without an expression is only permitted in a function whose return type is void. Production builds skip this block, but enabling UNIT_TESTING fails to compile. Change the bare return to `return NULL;` so test builds satisfy the function signature; production control flow is unchanged.

…anch Sonar c:S935 (CRITICAL): pubsub_connector_worker() is declared void *, but the conditional test-only early exit inside #ifdef UNIT_TESTING used a bare `return;`. Per C99/C11 6.8.6.4, a return without an expression is only permitted in a function whose return type is void. Production builds skip this block, but enabling UNIT_TESTING fails to compile. Same pattern as aws_kinesis.c:214 fixed in the previous commit.

…TING branch Sonar c:S935 (CRITICAL): exporting_main() is declared void, but the conditional test-only early exit inside #ifdef UNIT_TESTING used `return NULL;`, which is invalid for a void-returning function per C99/C11 6.8.6.4. Production builds skip the block, but enabling UNIT_TESTING fails to compile. Change the conditional return to a bare `return;`, and remove the stale "@return It always returns NULL" line from the function's docstring (left behind from when the signature was void *). Together with the previous two commits, this closes the c:S935 trio across the exporting subsystem (aws_kinesis, pubsub, exporting_engine).
