[dpdk-dev] [PATCH 2/2] bnx2x: fix to use SOCKET_ID_ANY for slowpath memory

When the DMA allocation routine is invoked in the context of a non-EAL
thread, the API rte_lcore_id() returns -1 and indexing on that in
rte_lcore_to_socket_id() leads to segfault. The fix is to use
SOCKET_ID_ANY as the socket_id for all slowpath memory allocation.

Fixes: 540a211 ("bnx2x: driver core")
