teamd: lacp: set port to disabled state during removal

Currently, the disabled state is set only after port is removed from
team master in kernel. Team driver puts the port netdevice down right
away. In some cases, there is nice to send LACPDU to the partner with
flags set accordingly for the disabled port.

Introduce "port_removing" op and call it right before kernel
is asked to remove the port. Implement the op in LACP runner
to disable the port which leads to proper LACPDU send.
