From: Jie Wang <wangjie125@huawei.com>

Currently keep alive message between PF and VF may be lost and the VF is
unalive in PF. So the VF will not do reset during PF FLR reset process.
This would make the allocated interrupt resources of VF invalid and VF
would't receive or respond to PF any more.

So this patch adds VF interrupts re-initialization during VF FLR for VF
recovery in above cases.

Fixes: 862d969a3a4d ("net: hns3: do VF's pci re-initialization while PF doing FLR")
