netlink/compat: Append NLMSG_DONE/extack to frag_list
Modules those use netlink may supply a 2nd skb, (via frag_list)
that contains an alternative data set meant for applications
using 32bit compatibility mode.
In such a case, netlink_recvmsg will use this 2nd skb instead of the
original one.
Without this patch, such compat applications will retrieve
all netlink dump data, but will then get an unexpected EOF.
