[PATCH v5 08/10] test-pmd: declare lcore_count atomic

[Andre Muezerie <andremue@linux.microsoft.com>]

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.
