[PATCH 2/3] mempool/cnxk: fix free from non-EAL pthreads

[Ashwin Sekhar T K]

From: Harman Kalra <hkalra at marvell.com>

For non-EAL pthreads, rte_lcore_id() will not be valid.
So, batch free cannot be used as those threads won't have
dedicated lmtlines. So, fallback to bulk alloc in such cases.

Fixes: ecbc731a2286 ("mempool/cnxk: add cn10k batch enqueue")
