wlan: Release intf addr before closing P2P adapter

A recent fix I6a5df12e8beec9237f8db19d675d40a17abc3d7c,
wlan_hdd_release_intf_addr is not called before closing the P2P adapter.
It will cause adapter failed to be opened due to failure to get intf addr.

Release intf addr before closing P2P adapter.
