[PATCH net-next v1] bonding: Fix another case of LACPDU not sent on slave

[Mahesh Bandewar <maheshb@google.com>]

When mii-mon discovers that the link is up, it will call
bond_3ad_handle_link_change() but we forget to add the LACP_ENABLED
flag when we discover the speed and duplex for the slave link are
normal.
