[dpdk-dev] [PATCH v2] bus/dpaa: fix memory allocation during bus scan

[Shreyansh Jain <shreyansh.jain@nxp.com>]

With the IOVA auto detection changes, bus scan is performed before
memory initialization. DPAA bus scan must not use rte_malloc in
its path.

Fixes: cf408c22476c ("eal: auto detect IOVA mode")
