  The 'state' in struct rte_eth_dev may be used to update some information
when app receive these events. For example, when app receives a new event,
app may get the socket id of this port by calling rte_eth_dev_socket_id to
setup the attached port. The 'state' is used in rte_eth_dev_socket_id.

If the state isn't modified to RTE_ETH_DEV_ATTACHED before pushing the new
event, app will get the socket id failed. So this patch moves pushing event
operation after the state updated.
