commit b00c9c39 removed the label end_of_netlink_messages and 'return
table' statement, It causes the function virArpTableGet doesn't return
a proper virArpTable pointer.
How to reproduce:
# virsh domiflist sles12sp3
Interface Type Source Model MAC
-------------------------------------------------------
vnet0 network default virtio 52:54:00:cd:02:e6
# virsh domifaddr sles12sp3 --source arp
error: Failed to query for interfaces addresses
error: An error occurred, but the cause is unknown
It seems that the "if (nh->nlmsg_type == NLMSG_DONE)" statement won't be
meted. So this patch adds 'return table' when the iterations of nlmsghdr
for loop is over.
