[dpdk-dev] [PATCH] test: fix incorrect cast in distributor unit test

[David Hunt]

New warning with gcc 8.1:
When casting the function pointer passed to
rte_eal_remote_launch() as an lcore_function_t *,
it expects the cast function to return an int, but
instead it was returning void. Fixed to return
an int.

Fixes: c3eabff124e6 ("distributor: add unit tests")
