[dpdk-dev] [PATCH v3] net/ice: fix segmentation fault with a wrong package

[Simei Su <simei.su@intel.com>]

This patch fixes core dump issue when entering safe mode with a
wrong ice.pkg. In safe mode, rte_flow is not supported and it
won't initialize any flow engine.

Fixes: 7615a6895009 ("net/ice: rework for generic flow enabling")
