[dpdk-dev] [PATCH v1 3/5] eal: modify device event callback process func

[Jeff Guo <jia.guo@intel.com>]

This patch modify the device event callback process function name to be
more explicit, and exposure the API from private to public. The drivers
and apps would directly use this API to process device event callback.
