ethdev: fix memory corruption with default Rx/Tx configuration

Commit fbde27f1 (get default Rx/Tx configuration from dev info),
introduced a bug, which caused memory corruption in dev_info.
To get RX/TX configuration, both rx/tx queue setup functions were calling
dev_info_get from PMDs, so dev_info structure was not being reseted
before being populated.
