[dpdk-dev] [PATCH] examples/quota_watermark: fix gcc 8.0.1 cast between incompatible types

[Reshma Pattan]

Gcc 8.0.1 reports incompatible cast between types i.e. from
`void (*)(void *)` to `(int (*)(void *)`.

Change the pipeline_stage prototype to retun int type
to fix the issue.

Fixes: a0ffcb257a ("examples/quota_watermark: correct code indentation")
