Bluetooth: mgmt: Add device disconnect reason
MGMT_EV_DEVICE_DISCONNECTED will now expose the disconnection reason to
userland, distinguishing four possible values:
0x00 Reason not known or unspecified
0x01 Connection timeout
0x02 Connection terminated by local host
0x03 Connection terminated by remote host
Note that the local/remote distinction just determines which side
terminated the low-level connection, regardless of the disconnection of
the higher-level profiles.
This can sometimes be misleading and thus must be used with care. For
example, some hardware combinations would report a locally initiated
disconnection even if the user turned Bluetooth off in the remote side.
