[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.
