In some cases, the DPDK does not allocate hugepage heap memory to
some sockets due to the user setting parameters
(e.g. -l 40-79, SOCKET 0 has no memory).
When the interrupt thread runs on the corresponding core of this
socket, each allocation/release will execute a whole set of heap
allocation/release operations,resulting in poor performance.
Instead we call malloc() to get memory from the system's
heap space to fix this problem.

Fixes: cb5c1b91f76f ("net/iavf: add thread for event callbacks")
