[PATCH v2] app/testpmd : fix testpmd quit error

[wenxuanx.wu at intel.com]

From: wenxuan wu <wenxuanx.wu at intel.com>

When testpmd use func get_eth_dev_info() while related resource
had been released.

Change the logic of func port_is_bonding_slave, this func 
eth_dev_info_get_print_err while pf is released would result 
in this error. Use ports instead to avoid this bug.

Fixes: 0a0821bcf312 ("app/testpmd: remove most uses of internal ethdev array")
