The uninitialized session has no peer associated with it yet. There is no point sending the failed message when abort the session. Sending the failed message in this case will send to a peer with uninitialized dst_cpu_id which will casue the receiver to pass a bogus shard id to smp::submit_to which cases segfault. In addition, to be safe, initialize the dst_cpu_id to zero. So that uninitialized session will send message to shard zero instead of random bogus shard id. Fixes the segfault issue found by repair_additional_test.py:RepairAdditionalTest.repair_abort_test Fixes #3115 Message-Id: <9f0f7b44c7d6d8f5c60d6293ab2435dadc3496a9.1515380325.git.asias@scylladb.com>
