From: Qiming Chen <chenqiming_huawei at 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/")
