Don't care about the power status of BT adapter before rfkill block.
(BT adapter is power on or off)
When rfkill unblock, BT will set the adapter power on.
It results in the following issue.
Connman can't control BT adapter power on/off rightly.
When using connman down BT, connman will send the dbus command
of power off and set rfkill block BT.
Power off BT: adapter power off -> rfkill block BT.
When using connman up BT, connman will set rfkill unblock BT
and send the dbus command of power on.
Power on BT: rfkill unblock adapter power on -> adapter power on.
When connman enable BT, BT adapter will power on after rfkill unblock.
After then, connman will receive the message of adapter property change.
The message is received before connman finish the message BT up to Bluez.
Thefore, the BT power status of connman is different with BT power status
in the message of adapter property change.
It will result in that connman send the dbus message of power off
to Bluez and power down BT adapter again.
