Subject: [Bluetooth] Support create connection cancel command
In case of non-blocking connects it is possible that the last user
of an ACL link quits before the connection has been fully established.
This will lead to a race condition where the internal state of a
connection is closed, but the actual link has been established and is
active. In case of Bluetooth 1.2 and later devices it is possible to
call create connection cancel to abort the connect. For older devices
the disconnect timer will be used to trigger the needed disconnect.

Subject: [Bluetooth]: Don't update disconnect timer for incoming connections
In the case of device pairing the only safe method is to establish
a low-level ACL link. In this case, the remote side should not use
the disconnect timer to give the other side the chance to enter the
PIN code. If the disconnect timer is used, the connection will be
dropped to soon, because it is impossible to identify an actual user
of this link.

Subject: [Bluetooth]: Fix section mismatch of bt_sysfs_cleanup()
The bt_sysfs_cleanup() is marked with __exit attribute, but it will
be called from an __init function in the error case. So the __exit
attribute must be removed.
