Constructing shared CARingBuffer cannot fail

This is a problem because shared CARingBuffers are used cross-process, and the WP might send data that would construct a potentially invalid CARingBuffer.
This leads to code that uses empty instances instead of not checking all use-sites correctly. This in turn leads to running code that is expected to only run when the ring buffer is correct.
