[dpdk-dev] [PATCH 1/2] eal/bsd: fix FreeBSD build

This function is part of the public API, so it should exist for FreeBSD, I think
instead of deleting the function we can add __rte_unused to parameters that are
not used to prevent build error.

With second check, rte_dev_event_callback_process() seems already implemented in
common, lib/librte_eal/common/eal_common_dev.c, and doesn't need linux/bsd
specific implementation, so adding this to bsdapp seems error at first place.

OK to remove function.
Fixes: 89ecd110524d ("eal: modify device event process function")

Agree, but then the commit message is misleading and should be reworded 
to indicate the real purpose of the fix.
