    net: ena: Remove deadcode

    ena_com_get_dev_basic_stats() has been unused since 2017's
    commit d81db24 ("net/ena: refactor ena_get_stats64 to be atomic
    context safe")

    ena_com_get_offload_settings() has been unused since the original
    commit of ENA back in 2016 in
    commit 1738cd3 ("net: ena: Add a driver for Amazon Elastic
    Network Adapters (ENA)")

    Remove them.
