[patch libteam] teamd/teamd_runner_lacp:PORT_STATE_DEFAULTED use 0x02

[Meng Koon Lim]

if new state is PORT_STATE_DEFAULTED, set lacp_port->partner.state
to 0x02

This ensures LACPDU is sent to update the far side when
local port transitions from default to current

Currently, local port moves from default to current without
sending LACPDU until 30sec later. This causes traffic disruption
because far side has not completed negotiation

Using 0x02 also cause LACPDU to be sent every 1 sec as long as
port remains in defaulted state and LACP mode used is "active"

Please try to re-phrase the subject and the decription in imperative
way. Like you would tell the codebase what do to. Please look at the git
log for inspiration. Thanks!
