[dpdk-dev] [PATCH v1] net/mlx4: fix missing initializers for old GCC

[Moti Haimovsky]

This patch works around compilation issues seen on RHEL 7.2
using GCC 4.8.5:

   [...] In function 'mlx4_rss_init':
   [...]/mlx4_rxq.c:433:19: error: 'wq_num' may be used uninitialized
        in this function [-Werror=maybe-uninitialized]

Fixes: ff3397e90080 ("net/mlx4: relax Rx queue configuration order")
