Subject: [PATCH] rxrpc: remove duplicate 'error' variable

The rxrpc_process_call function has debug code to print a failure code,
but instead of printing the code from the rxrpc_call structure, it
prints an uninitialized variable:

net/rxrpc/call_event.c: In function 'rxrpc_process_call':
net/rxrpc/call_event.c:879:58: error: 'error' may be used uninitialized in this function [-Werror=maybe-uninitialized]

This removes the extraneous variable and prints the correct
code instead.

Signed-off-by: Arnd Bergmann <arnd@...db.de>
Fixes: f5c17aaeb2ae ("rxrpc: Calls should only have one terminal state")
