[PATCH v3 17/46] nl80211: Use wdev-based message for SET_KEY on wdev-only interfaces

[Kavita Kavita]

From: Peddolla Harshavardhan Reddy <peddolla.reddy at oss.qualcomm.com>

The pairwise RX/TX modify path in wpa_driver_nl80211_set_key()
always used nl80211_ifindex_msg() which includes NL80211_ATTR_IFINDEX.
Non-netdev interfaces such as PD (Proximity Detection) have no valid
ifindex, causing SET_KEY to fail.

Use nl80211_cmd_msg() instead when the interface is not a netdev type
so that NL80211_ATTR_WDEV is included in the SET_KEY command.
