According to the documentation, rte_eth_dev_configure() can be invoked repeatedly while in stopped state. The current implementation in the bonding driver allows for that (technically), but the user sees warnings which say that back-end devices have already been harnessed. Re-factor the code to have cleanup before each (re-)configure.
