[dpdk-dev] [PATCH] net/i40e: fix vsi removing from tailq when release

[Jingjing Wu]

VSI structure need to be removed from TAILQ list when releasing.
But for the child VSI it will be removed again after the structure
is freed. It will cause core dump when the DPDK i40e using as PF
host driver.

This patch fixes it to only remove child VSI from TAILQ before
send adminq command to remove it from hardware.
