Subject: [PATCH] Fix disconnect devices after enabling offline mode

Previously paired and connected devices were disconnected automatically
after turning bluetooth off directly via bluetooth UI. This patch makes
that also other ways of turning bluetooth off (which should lead to
disconnecting paired and connected devices), such as enabling offline
mode (which turns bluetooth off as well), can be handled properly.
