[ Upstream commit 09e6b30eeb254f1818a008cace3547159e908dfd ]
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.
