rpc,glusterd: Use rpc_clnt notifyfn to cleanup mydata
rpc: - On a RPC_TRANSPORT_CLEANUP event, rpc_clnt_notify calls the registered notifyfn with a RPC_CLNT_DESTROY event. The notifyfn should properly cleanup the saved mydata on this event. - Break the reconnect chain when an rpc client is disabled. This will prevent new disconnect events which can lead to crashes. glusterd: - Added support for RPC_CLNT_DESTROY in glusterd_brick_rpc_notify - Use a common glusterd_rpc_clnt_unref() function throught glusterd in place of rpc_clnt_unref(). This function correctly gives up the big-lock before performing the unref.
