wifi: mac80211: Get the correct interface for non-netdev skb status

The function ieee80211_sdata_from_skb() always returned the P2P Device
interface in case the skb was not associated with a netdev and didn't
consider the possibility that an NAN Device interface is also enabled.

To support configurations where both P2P Device and a NAN Device
interface are active, extend the function to match the correct
interface based on address 2 in the 802.11 MAC header.

Since the 'p2p_sdata' field in struct ieee80211_local is no longer
needed, remove it.
