Zsolt Gaál ddc67b681e examples: Fix cleanup waterfall memory leak in rx_samples_c 
This PR fixes a bug in the goto cleanup waterfall within rx_samples_c.

Previously, the free_rx_streamer label was positioned above the
free_rx_metadata label. Because C executes sequentially, if an error
occurred after the metadata was successfully created (for example,
during uhd_usrp_set_rx_rate or uhd_usrp_get_rx_stream), the code would
jump to free_rx_metadata, fall through to free_usrp, and exit. It
completely skipped free_rx_streamer, silently leaking the streamer
memory and leaving the hardware handles dangling.

Changes:

- Reordered the cleanup labels to strictly follow the reverse-chronological
  order of resource creation (Metadata -> Streamer -> USRP).
- Updated the corresponding EXECUTE_OR_GOTO jump targets for the stream
  setup functions to match the new waterfall order.
