[Bluetooth] Signal user-space for HIDP and BNEP socket errors
When using the HIDP or BNEP kernel support, the user-space needs to know if the connection has been terminated for some reasons. Wake up the application if that happens. Otherwise kernel and user-space are no longer on the same page and weird behaviors can happen. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
