Set LE called when hdev is up but still has HCI_AUTO_OFF flag set will
only change dev_flags and enable feature in host but won't enable feature
in controller. As a resulit it's not possible to e.g. start LE only or
interleaved discovery due to missing LE Supported flag in local features.
This patch ensures HCI Write LE Host Supported is sent when Set Powered is
called to clear HCI_AUTO_OFF flag.
