  [8087:0a2b] Failed to load bluetooth firmware(might affect some other

Bug description:
  [Impact]
  After this linux-firmware bug[1] update the firmware files, it removes intel/ibt-11-16.{ddc,sfi} and add intel/ibt-12-16.{ddc,sfi}, but in btusb driver, it hardcoded the hw_variant as 11. So we got this kind of error after the linux-firmware package updated and lost the bt functions.

  [    5.516003] Bluetooth: hci0: Minimum firmware build 1 week 10 2014
  [    5.516181] bluetooth hci0: Direct firmware load for intel/ibt-11-16.sfi failed with error -2
  [    5.516183] Bluetooth: hci0: Failed to load Intel firmware file (-2)

  [Fix]
  This patch uses a hw_variant variable to replace the hardcoded 11.

  [Test Case]
  Verified on the machine has this issue, and confirm this patch works.

  [Regression Potential]
  The hw_variant variable has shown up since kernel 3.10 in this commit
     dffd30e Bluetooth: Add support for Intel Bluetooth device [8087:07dc]
  So, we don't have to worry about old chips don't contains this info, since it exists
  and be used for a very long time.
