  A segmentation fault occurs when testpmd exit.

This is due to fetching the device name from PF
, PF is freed firstly and then VF representor
is called later.

This commit fixes the bug by fetching the device
name from vf representor not PF.

The title talks about testpmd, but the change is in i40e.
Please update.

For info, a comma must follow the previous word without any space.
It is strange to see a comma at the beginning of a line.

vf should be VF uppercase
