From: Xuanqiang Luo <luoxuanqiang at kylinos.cn>

Commit 4c1a457cb8b0 ("iavf: add support to exchange qos capabilities")
allocates adapter->qos_caps during probe, but iavf_remove() does not
free it. This leaks the allocation whenever an iavf device is removed.

Free adapter->qos_caps in iavf_remove().
