You call this function (cb_cleanup) only at dev_confiture().
At that moment DP threads can't do enqueue/dequeue anyway.
So you can safely skip all this synchronization code here and just do:

cb = list->next;
while (cb != NULL) {
	next = cb->next;
	rte_free(cb);
	cb = next;
}


> +			rte_free(curr_cb);

One thing that makes it sort of grey area:
we do free() for cb itself, but user provided data will be sort of 'lost'.
As it is not referenced from our cb struct anymore...
I see two options here - first just document explicitly that callbacks wouldn't
survive cryptodev_configure() and it is user responsibility to remove all
installed callbacks before doing dev_configure() to avoid possible memory leakage.
Another option - add user provided cleanup() function pointer into struct rte_cryptodev_cb
and call it here if provided:
struct rte_cryptodev_cb {
	struct rte_cryptodev_cb *next;
	/** < Pointer to next callback */
	rte_cryptodev_callback_fn fn;
	/** < Pointer to callback function */
	void *arg;
	/** < Pointer to argument */
	void (*cleanup)(void *);	
};

And here:
	If (curr_cb->cleanup != NULL)
		curr_cb->cleanup(curr_cb->arg);

 	rte_free(curr_cb);

Rest of the code - LGTM.
So with that addressed:
