[PATCH BlueZ] Fix release all sessions on powering adapter off

[Dmitriy Paliy <dmitriy.paliy@nokia.com>]

When adapter is powered off, all sessions should be released without
changing mode, which is contrary to what session_remove does. This
prevents from such situation when powering off leads to new mode
derived from mode_sessions.

Currently, if there are multiple mode sessions requested by different
clients, powering adapter off results in powering immediately it on.
