[PATCH] lib/eal: fix macros for noinline and alwaysinline for MSVC

[Andre Muezerie]

From: Andre Muezerie <andremue@ntdev.microsoft.com>

MSVC supports forcing code to be inlined or forcing code to not be
inlined, like other compilers.

This patch fixes existing macros __rte_noinline and
__rte_always_inline so that they also do what is expected from them
when used with MSVC.
