[dpdk-dev] [PATCH 2/3] eal: fix remove incorrect event_cb

[wangyunjian <wangyunjian@huawei.com>]

From: Yunjian Wang <wangyunjian@huawei.com>

When the device_name is NULL, it will remove the event_cb directly.
We need to compare the 'cb_fn' and 'cb_arg' at the same time.

Fixes: a753e53d517b ("eal: add device event monitor framework")
