Bluetooth: hci_sync: Fix not setting static address

Browse Source 
This attempts to program the address stored in hdev->static_addr after
the init sequence has been complete:

@ MGMT Command: Set Static A.. (0x002b) plen 6
        Address: C0:55:44:33:22:11 (Static)
@ MGMT Event: Command Complete (0x0001) plen 7
      Set Static Address (0x002b) plen 4
        Status: Success (0x00)
        Current settings: 0x00008200
          Low Energy
          Static Address
