[PATCH 20.11 V2] app/testpmd: fix port status of bonding slave device

[Huisong Li <lihuisong@huawei.com>]

[ upstream commit e46372d7b082706718bb17981ae632e4e4d56414 ]

Starting or stopping a bonded port also starts or stops all active slaves
under the bonded port. If this port is a bonded device, we need to modify
the port status of all slaves.

Fixes: 0e545d3047fe ("app/testpmd: check stopping port is not in bonding")
