[PATCH] app/test: fix retest link bonding fail

[Jie Hai]

The testcase "test_close_bonding_device" closes the bonding
port shared by several cases. After closed, the port is in
RTE_ETH_DEV_UNUSED state, and could not be used by other cases
anymore. If retest the "link_bonding_autotest", failure occurs.
This patch creates a new bonding device for the closing testcase.
