[Bluetooth] Support concurrent connect requests
Most Bluetooth chips don't support concurrent connect requests, because this would involve a multiple baseband page with only one radio. In the case an upper layer like L2CAP requests a concurrent connect these chips return the error "Command Disallowed" for the second request. If this happens it the responsibility of the Bluetooth core to queue the request and try again after the previous connect attempt has been completed.
