[PATCH] device: Fix Connect and ConnectProfile returing InProgress error

[Szymon Janc]

Calling Connect or ConnectProfile for device without resolved services
results in doing SDP browse first. After search is complete code was
suppose to continue with profile connection but was always returning
"InProgress" error due to browsing request not being cleared yet.
