Subject: [PATCH net] rxrpc: Fix an uninitialised variable

Fix an uninitialised variable introduced by the last patch.  This can cause
a crash when a new call comes in to a local service, such as when an AFS
fileserver calls back to the local cache manager.

Fixes: c1e15b4944c9 ("rxrpc: Fix the packet reception routine")
