Fix rc connect fail after remove bond

[Description]
Fix sometimes not notify framework connection status issue

[Root Cause]
when DUT is direct connect to RC, user remove bond of the RC.
whatever the RC connected or disconnected, it will not notify
framework the connection status, because bta_hh device will
be clear when remove bond.

[Solution]
so when remove bond and pending device is the connecting device,
then notify the framework disconnected, and cancel direct connect.
