[PATCH v1 1/1] eal/random: fix random state initialization for non-eal threads

[Anatoly Burakov <anatoly.burakov@intel.com>]

Currently, the rte_rand() state is initialized with seed, and each
rand state is initialized up until RTE_MAX_LCORE'th rand state. However,
rand state also has one extra rand state reserved for non-EAL threads,
which is not initialized. Fix it by initializing this extra state.

Fixes: 3f002f069612 ("eal: replace libc-based random generation with LFSR")
