[PATCH 7/9] net/dpaa2: fix Rx queue count for primary process

[Maxime Leroy]

The rx_queue_count callback was only assigned on the secondary process
path of dpaa2_dev_init(), leaving eth_dev->rx_queue_count NULL for the
primary process. The fast-path rte_eth_rx_queue_count() performs an
unguarded indirect call in non-debug builds, so invoking it on a
primary-process dpaa2 port dereferences a NULL function pointer and
crashes.

Assign the callback once before the process-type split so both the
primary and secondary paths set it.
