[BlueZ PATCH] tools: userchan-tester: Add test case for the closing channel

[Tedd Ho-Jeong An <hj.tedd.an@gmail.com>]

From: Tedd Ho-Jeong An <tedd.an@intel.com>

This patch adds a test casse for checking the controller power state
after closing the user channel.

When the user channel is closed, the controller should be powered down
state.
