The RFCOMM tty device is parented to the acl link device when the dlc state_change(BT_CONNECTED) notification is received. However, if the dlc from the RFCOMM socket is being reused (RFCOMM_REUSE_DLC is set), then the dlc may already be connected, and no notification will occur. Instead, always parent the RFCOMM tty device to the acl link device at registration time. If the acl link device is not available (eg, because the dlc is not connected) then the tty will remain unparented until the BT_CONNECTED notification is received. Fixes regression with ModemManager when the rfcomm device is created with the flag RFCOMM_REUSE_DLC.
