[PATCH] P2P: Fix Dbus property getters to default to "/" for Group, PeerGO

[nirav shah]

The Dbus property getters should not return an error when the
properties are not valid/relevant. Returning an error breaks the
GetAll method in the dbus interface. Changing Group and PeerGO
property getters to make GetAll work on P2PDevice.
