input: Fix workaround for broken hardware keyboard support

Using a wrong reference to mHardKeyboardAvailable caused device config
to never report physical keyboards.

Change-Id: I9b64e2d89512436c17fa8929464e2b727fba1cf3
Framework: Forward port ADB over network (Part 2 of 2)

Includes:
- ADB Over Network, integration of the adb-host mode (already present)
  The feature can be used/tested without the Settings part:

    setprop service.adb.tcp.port 5555

  Note: This ADB setting is not persistent (for security purpose) and
  require init.rc implementation event like this : http://bit.ly/AdbTcpIP
