The memory allocated with _aligned_malloc()
must be released with _aligned_free() on Windows.
The POSIX free() was called in eal_lcore_var_cleanup(),
called in rte_eal_cleanup(), and triggered a heap corruption:
exit status 3221226356 or signal 3221226228 SIGinvalid
with MALLOC_PERTURB_=86
Fixes: 5bce9bed67ad ("eal: add static per-lcore memory allocation facility")
