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

[Ashwin Sekhar T K]

For non-EAL pthreads, rte_lcore_id() will not be valid.
So, batch allocation cannot be used as we won't have a
dedicated alloc buffer for the thread. So, fallback to
bulk alloc in such cases.

Fixes: 91531e63f43b ("mempool/cnxk: add cn10k batch dequeue")
