[PATCH] eal: fix msvc conditional compile of rte atomic thread fence

[Tyler Retzlaff]

MSVC does not expose legacy atomics. When the legacy atomics were
excluded rte_atomic_thread_fence was also unintentionally excluded

Adjust the conditional compilation check to expose
rte_atomic_thread_fence.

Fixes: 27da6a123414 ("eal: hide legacy atomics API for MSVC")
