rpc: bump up conn->cleanup_gen in rpc_clnt_reconnect_cleanup
Commit 086436a introduced generation number (cleanup_gen) to ensure that
rpc layer doesn't end up cleaning up the connection object if
application layer has already destroyed it. Bumping up cleanup_gen was
done only in rpc_clnt_connection_cleanup (). However the same is needed
in rpc_clnt_reconnect_cleanup () too as with out it if the object gets destroyed
through the reconnect event in the application layer, rpc layer will
still end up in trying to delete the object resulting into double free
and crash.
Peer probing an invalid host/IP was the basic test to catch this issue.
