Bluetooth: Sync Bluetooth Adapter and Manager Service.

BluetoothAdapter has timeout of 8 sec whereas waittime of
Bluetooth Manager Service has timeout of 3 seconds, case
if remote does not responds to service level  disconnection
then Mangaer Service times out after 3 sec.
During multiuser switch new process is created hence
previous process cannot block ON thus one process is waiting
for timout and other process tries to Turn BT ON leading to
crash.
Fix involve is to have Adapter and Manager service
have same timeout during user switch.
