doc: announce ethdev functions will not return void
void return value is bad for get API (like rte_eth_dev_info-get()) since caller does not know if the function does its job or not and output value is filled in. void return value is bad for state changing API (like rte_eth_promiscuous_enable()) since caller should use get API to understand if state is really changed.

Target release for removal of the legacy API will be defined once most
PMDs have switched to rte_flow.
+* ethdev: Update API functions returning ``void`` to return ``int`` with
+ negative errno values to indicate various error conditions (e.g.
+ invalid port ID, unsupported operation, failed operation):
+ - ``rte_eth_dev_info_get``
+ - ``rte_eth_promiscuous_enable`` and ``rte_eth_promiscuous_disable``
+ - ``rte_eth_allmulticast_enable`` and ``rte_eth_allmulticast_disable``
+ - ``rte_eth_link_get`` and ``rte_eth_link_get_nowait``
+ - ``rte_eth_dev_stop``
+ - ``rte_eth_dev_close``
+ - ``rte_eth_xstats_reset``
+ - ``rte_eth_macaddr_get``
+ - ``rte_eth_dev_owner_delete``
* cryptodev: support for using IV with all sizes is added, J0 still can
be used but only when IV length in following structs ``rte_crypto_auth_xform``,
``rte_crypto_aead_xform`` is set to zero. When IV length is greater or equal
