Fix invitation request from persistent GC

When the device received the second invitation request
from GC of the same PersistentGroup, the wifi framework
processes "sa" as mOwner of WifiP2pGroup. At this point,
if an invited group is persistent group, WifiP2pGroup can't
know whether "sa" is GC or GO yet. So the framework shouldn't
process mOwner in the constructor.
