The original patch from Lin Ma enables the vdpa driver to use validation
netlink ops.
The second patch simply disables the validation skip which is no longer
neccesary. Patchset started of from this discussion [0].

From: Lin Ma
The vdpa_nl_policy structure is used to validate the nlattr when parsing
the incoming nlmsg. It will ensure the attribute being described produces
a valid nlattr pointer in info->attrs before entering into each handler
in vdpa_nl_ops.
That is to say, the missing part in vdpa_nl_poli
The previous patch added the missing nla policies that were required for
validation to work.
Now strict validation on netlink ops can be enabled. This patch does it.

The ndev was accessed on shutdown without a check if it actually exists.
This triggered the crash pasted below. This patch simply adds a check
before using ndev.
