Description
This PR fixes multiple instances of compiler warning C4098 in src/lib_ccx/networking.c.
Several functions (connect_to_srv, net_send_header, etc.) were declared as void but were attempting to return values from internal function calls.

Changes

• Casted the return values of the internal Rust functions to (void) to suppress MSVC warning C4098.

• Removed the explicit return; statements to ensure the subsequent C implementation is correctly executed (fixing a logic error where the C fallback was being skipped).

Environment

• Windows 11
• MSVC / CMake

Thank you for the fix! However, there's a logic issue.

The original return ccxr_xxx(); was intentional - it calls Rust and returns early so the C fallback doesn't execute. Your fix for net_check_conn is correct:

ccxr_net_check_conn();
return;

But the other 3 functions are missing the return;, so both Rust AND C code will execute when Rust is enabled.

Please add return; after the Rust calls in:

• connect_to_srv
• net_send_header
• net_send_epg

Thanks for the review! I've added the missing return; statements to connect_to_srv, net_send_header, and net_send_epg as requested. Ready for re-review.
