Subject: bonding: update LACP activity flag after setting lacp_active

From: Hangbin Liu <liuhangbin@gmail.com>

[ Upstream commit b64d035f77b1f02ab449393342264b44950a75ae ]

The port's actor_oper_port_state activity flag should be updated immediately
after changing the lacp_active option to reflect the current mode correctly.

Fixes: 3a755cd8b7c6 ("bonding: add new option lacp_active")
