commit aadf9dcef9 upstream.
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: b54a134a7d ("rxrpc: Fix handling of enums-to-string translation in tracing")
