[PATCH BlueZ] Fix removing inotify watch whenever an adapter is removed

[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

This sometimes cause bluetoothd to burn cpu when an adapter is removed
from the system.

Since the watch is not really bond to any adapter, in fact it is added on
plugin .init, its removal is now moved to plugin .exit.
