[dpdk-stable] [PATCH] net/tap: fix MAC addr when flower support is disabled

[Ferruh Yigit <ferruh.yigit@intel.com>]

From: Vipin Varghese <vipin.varghese@intel.com>

When flower_support disabled, API returns without setting MAC address,
this patch sets MAC address for that case.

Fixes: de96fe68ae95 ("net/tap: add basic flow API patterns and actions")
Cc: stable@dpdk.org

This patch is for 17.05 stable release. In master this issue already
solved because flower_support removed.
