iwmc3200wifi: fix NULL pointer dereference in iwm_if_free
The driver private data is now based on wiphy. So we should not touch the private data after wiphy_free() is called. The patch fixes the potential NULL pointer dereference by making the iwm_wdev_free() the last one on the interface removal path. Signed-off-by: Zhu Yi <yi.zhu@intel.com> Signed-off-by: John W.
