[PATCH v5 1/2] ethdev: fix ethdev configuration state on reset

[Hanumanth Pothula]

Presently, on device reset, ethdev configuration state,
dev_configured, is not reset.

On device reset, reset ethdev configuration state to make
sure device reconfiguration happens cleanly.

v5:
 - Move nic-to-pmd-rx-metadata declaration to struct rte_port.
v4:
 - As per spec rte_eth_rx_metadata_negotiate() is processed only when
   dev_configured is set. Hence can't enable automatically when a flow
   command requests metadata.
 - Add new testpmd command to allow NIC to PMD Rx metadata negotiation.
v3:
 - Updated run_app.rst with the new command line argument,
   nic-to-pmd-rx-metadata.
 - Updated commit text.
v2:
 - taken cared alignment issues
 - renamed command line argument from rx-metadata to nic-to-pmd-rx-metadata
 - renamed variable name from rx-metadata to nic_to_pmd_rx_metadata
