Show reboot dialog when tunring off developer option

The toggle button "Disable Bluetooth A2DP hardware offload" in developer
options need reboot to take effect when value changed. Otherwise, the
A2DP will not work until user reboot the device.

If we want this toggle button change back to default value when turning
off developer options, we need reboot device as well.

This patch will check the property value of A2DP hardware offload. If
turning off developer options will change the value, show a dialog to
force the user to reboot device.
