[PATCH 08/10] test-pmd: declare lcore_count atomic when using C11 memory model

[Andre Muezerie]

Compiling with MSVC results in the error below:

app/test/test_ring_perf.c(197): error C7712: address argument to atomic
    operation must be a pointer to an atomic integer,
    'volatile unsigned int *' is not valid

The fix is to mark lcore_count as atomic when using C11 memory model.
