net: ethtool: re-order local includes

Most local #include in the ethtool command handling is out of order,
with either :

 #include "netlink.h"
 #include "common.h"

or even :

 #include "netlink.h"
 #include "common.h"
 #include "bitset.h"

One of the reasons is because bitset.h s lacking definitions for
nlattr, netlink_ext_ack, ETH_GSTRING_LEN, and types such as u32, bool,
etc.

Make bitset.h standalone by including <linux/ethtool.h> for
ETH_GSTRING_LEN, and <linux/netlink.h> for nlattr, netlink_ext_ack and
the rest.

While at it, take a pass on ethnl sources to re-order the local
includes :
 - put them after the global includes
 - add a newline between global and local includes
 - alpha-sort the local includes

One notable exception is the cmis.h include, that needs definitions from
module_fw.h. Keep them in this order for now.
