kobject_init_and_add() takes reference even when it fails.
If this function returns an error, kobject_put() must be called to
properly clean up the memory associated with the object. Previous
commit "b8eb718348b8" fixed a similar problem.
Fixes: 07699f9a7c ("bonding: add sysfs /slave dir for bond slave devices.")

Bond expects ethernet hwaddr for its slave, but it can be longer than 6
bytes - infiniband interface for example.
# cat /sys/devices/<skipped>/net/ib0/address
80:00:02:08:fe:80:00:00:00:00:00:00:7c:fe:90:03:00:be:5d:e1
# cat /sys/devices/<skipped>/net/ib0/bonding_slave/perm_hwaddr
80:00:02:08:fe:80
So print full hwaddr in sysfs "bonding_slave/perm_hwaddr" as well.

Prefer the direct use of octal for permissions.
Done with checkpatch -f --types=SYMBOLIC_PERMS --fix-inplace
and some typing.
Miscellanea:

Export the partner_oper_port_state of each port via sysfs and netlink.
In 802.3ad mode it is valuable for the user to be able to check the
partner_oper state, it is already exported via bond's proc entry.

Otherwise the name of the kobject isn't getting freed and other stuff from
kobject_cleanup() isn't getting called. kobject_put() will call
kobject_del() on its own in kobject_cleanup().

The struct ad_slave_info is very huge, and only be used for 802.3ad mode,
so alloc the structure dynamically could save 356 Bits for every slave in
non 802.3ad mode.
