testpmd will occur infinite loops when device hotplug remove.
We can fix the issue by using the pci generic remove function

Fixes: f2f4990eff94 ("net/ixgbe: release port upon close")

v4:
used generic remove function for ixgbe_vf_representor_uninit.
v3:
reverted the code about ixgbe_vf_representor_uninit.
