Bluetooth: Do not send SET_EVENT_MASK for 1.1 and earlier devices

Browse Source 
Some old hci controllers do not accept any mask so leave the
default mask on for these devices.

< HCI Command: Set Event Mask (0x03|0x0001) plen 8
    Mask: 0xfffffbff00000000
> HCI Event: Command Complete (0x0e) plen 4
    Set Event Mask (0x03|0x0001) ncmd 1
    status 0x12
    Error: Invalid HCI Command Parameters
