wifi: cfg80211: wext: hold wiphy lock in siwgenie
Missed this ioctl since it's in wext-sme.c where we usually get via a front-level ioctl handler in the other files, but it should also hold the wiphy lock to align the locking contract towards the driver. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
