Bluetooth: Fix potential memory leak
If command is added to req then it should be freed in case if
hdev is down or HCI_ADVERTISING flag is set.
This introduces a helper in hci_request to purge the cmd_q
to make cmd_q internal to hci_request which is used to fix
the leak.
This also replace accessing of cmd_q in hci_conn with the
new helper.
