Subject: [EXT] [PATCH] net/mvpp2: fix non-EAL thread support

External Email

----------------------------------------------------------------------
Caught by code inspection, for a non-EAL thread identified with
rte_lcore_id() == LCORE_ID_ANY, the code currently arbitrarily uses lcore 0 while there is no guarantee this lcore is used.

Fixes: 3588aaa68eab ("net/mrvl: fix HIF objects allocation")
