Currently, some eth devices are added to bond device, these devices are not
released when the quit command is executed in testpmd. This patch adds the
release operation for all active slaves under a bond device.

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

Hi Connor,

Can you please do the similar #ifdef grouping done in 3/5 patch?
