When testpmd quits with two ports, the second port's MAC address
remains in the MAC table of switch manager.
There should be some time for HW to quiesce when closing a port,
otherwise the subsequent port close won't be handled correctly.
This patch adds some delay after turning off a logic port, just as
what the kernel driver does.
Fixes: 8b5c9ec20b7b ("support VMDQ in MAC/VLAN filter")
