This patch fixes heap-use-after-free reported by ASAN,
please reference https://bugs.dpdk.org/show_bug.cgi?id=869

The application can use the queue_id as `-1` to delete all
the queues of the eth_device that are added to tx_adapter
instance.
In above case, the queue_del api is trying to use number of
queues from adapter level instead of eth_device queues.
When there are queues added from multiple eth devices,
it will result in heap-use-after-free as reported by ASAN.

This patch fixes the queue_del api to use correct number of
queues.

Updated the commit log as:

    eventdev/eth_tx: fix queue delete logic

    This patch fixes heap-use-after-free reported by ASan.

    The application can use the queue_id as `-1` to delete all
    the queues of the eth_device that are added to tx_adapter
    instance.
    In above case, the queue_del API is trying to use number of
    queues from adapter level instead of eth_device queues.
    When there are queues added from multiple eth devices,
    it will result in heap-use-after-free as reported by ASAN.

    This patch fixes the queue_del API to use correct number of
    queues.
