[PATCH] cryptodev: fix crypto op bulk alloc Doxygen

When calling rte_crypto_op_bulk_alloc, the function may
return either a 0, if not enough objects are available
in the mempool or the number of operations requested,
it there are enough available. However, the Doxygen comments
were not matching these two cases.
