Devlink commands which implements the dumpit callback may return error.
The netlink function netlink_dump() sends the errno value as the payload
of the message, while answering user space with NLMSG_DONE.
To enable receiving errno value for dumpit commands we have to check for
it in the message. If it is a negative value then the dump returned an
error so we should set errno accordingly and check for ext_ack in case
it was set.
