[PATCH net 1/3] rxrpc: Fix trace string

[David Howells]

The trace symbol printer (__print_symbolic()) ignores symbols that map to
an empty string and prints the hex value instead.

Fix the symbol for rxrpc_cong_no_change to " -" instead of "" to avoid
this.

Fixes: b54a134a7de4 ("rxrpc: Fix handling of enums-to-string translation in tracing")
