rxrpc: kdoc: Update function descriptions and add link from rxrpc.rst

Update the kerneldoc function descriptions to add "Return:" sections for
AF_RXRPC exported functions that have return values to stop the kdoc
builder from throwing warnings.

Also add links from the rxrpc.rst API doc to add a function API reference
at the end.  (Note that the API doc really needs updating, but that's
beyond this patchset).
