[dpdk-dev] [PATCH] net/i40e: fix vf resource leakage problem

[chenqiming_huawei]

From: Qiming Chen <chenqiming_hua...@163.com>

In the i40evf_dev_init function, when the MAC memory alloc fails, the
previously initialized vf resource is not released, resulting in leakage.
The patch calls the i40evf_uninit_vf function in the abnormal branch to
release resources.

Fixes: 5c9222058df7 ("i40e: move to drivers/net/")
Cc: sta...@dpdk.org
