[PATCH] iw: rename nl_handle to nl_sock for libnl-2.0

[pat-lkml <pat-lkml@erley.org>]

Upstream has renamed nl_handle to nl_sock.  Update iw to the new names
and add #define for libnl-1.1.

Signed-off-by: Pat Erley <pat-lkml@erley.org>

In the future, should I keep pushing these sorts of patches, or should
we back them out and wait for a 'release' of libnl-2.0 and push them all
in then?
