Mattias Rönnblom eb13e558f8 eal: add macro to warn for unused function return values
This patch adds a wrapper macro __rte_warn_unused_result for the
warn_unused_result function attribute.

Marking a function __rte_warn_unused_result will make the compiler
emit a warning in case the caller does not use the function's return
value.
