[dpdk-dev] [PATCH v3] drivers/net/i40e: fix missing promiscuous disable at device disable

[Rosen Xu <rosen.xu@intel.com>]

v3 updates:
===========
 - Move modification from device close to device disable
 - i40evf_reset_vf() will cause kernel driver enable all vlan promiscuous,
   so unicast/multicast promiscuous disable should set before reset.

v2 updates:
===========
 - Add more comments

In scenario of Kernel Driver runs on PF and PMD runs on VF, PMD exit
doesn't disable promiscuous mode, this will cause vlan filter set by
Kernel Driver will not take effect.

This patch will fix it, add promiscuous disable at device disable.
