P2P: Updates the P2P peer list when there is P2P State Change Action

In the current implementation the P2P window gets updated with the
Peers list only when there is WIFI_P2P_PEERS_CHANGED_ACTION Intent.
Thus the P2P status remains unchanged when there is
WIFI_P2P_STATE_CHANGED_ACTION intent. When there is back and forth
navigation to P2P window, WIFI_P2P_STATE_CHANGED_ACTION intent invokes
the onPeersAvaliable function asynchronously and updates the P2P status
and peers list.

Bluetooth: Fix to connect PANU from the internet access menu

isPrefered is always true for PAN. So PANU connect fails,
Once user clicks on the internet access menu in Profiles
Setting. As PAN is not auto connect profile, So PANU should
connect from the internet access menu in Profiles Setting.
