Title:
  vrf: fix refcnt leak with vxlan slaves

Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Bionic:
  Fix Released
Status in linux source package in Focal:
  Fix Released

Bug description:
  [Impact]

  There are cases, where deleting a VRF device can hang waiting for the refcnt 
to drop to 0, with the message: 
    unregister_netdevice: waiting for vrf1 to become free. Usage count = 1

  This is fixed upstream with commit b87b04f5019e ("ipv4: Fix device
  used for dst_alloc with local routes"), included in linux v5.13. The
  original patch, which has introduced the bug, is included in linux
  v4.10.

  
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=b87b04f5019e

  [Test Case]

  The upstream patch includes a test case, which describe how to
  reproduce the bug.

  [Regression Potential]

  The patch affects ipv4 routing. It is straightforward, it links new
  dst to a vrf device instead of the loopback if needed.
