====================
net: genetlink: parse attrs for dumpit() callback

In generic netlink, parsing attributes for doit() callback is already
implemented. They are available in info->attrs.

For dumpit() however, each user which is interested in attributes have to
parse it manually. Even though the attributes may be (depending on flag)
already validated (by parse function).

Make usage of attributes in dumpit() more convenient and prepare
info->attrs too.

Patchset also make the existing users of genl_family_attrbuf() converted
to use info->attrs and removes the helper.
