Bluetooth: Remove unneeded mgmt_connectable function
The mgmt_connectable function has been used to ensure that the right actions to HCI_CONNECTABLE are taken when the HCI_Write_Scan_Enable command is triggered by something else than mgmt. The only other user that we really care about is the HCISETSCAN ioctl code, so we can actually more simply perform the needed changes there instead.
