Bluetooth: Do not send SET_EVENT_MASK for 1.1 and earlier devices
Some old hci controllers do not accept any mask so leave the
default mask on for these devices.

Mask: 0xfffffbff00000000
> HCI Event: Command Complete (0x0e) plen 4
Set Event Mask (0x03|0x0001) ncmd 1
status 0x12
Error: Invalid HCI Command Parameters
