app/testpmd : fix testpmd quit error
Checks
Commit Message
From: Wenxuan Wu <wenxuanx.wu@intel.com>
when testpmd startup with pf and vfs, it is ok when running, while
exiting, it will result in heap-free-after-use which means pf is
released but vf is still accessing.
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.
Fixes: 0a0821bcf312 ("app/testpmd: remove most uses of internal ethdev array")

Removing call to func eth_dev_info_get_print_err, seems like a quick fix to the problem.
Can you try root causing further, where pf is released. And can the order be fixed,
first free vf and then the pf.
