Bug description:
  == SRU Justification ==
  [Impact]
  Some QCA ROME bluetooth devices does not work after runtime suspend/resume after SRU LP: #1734020.

  [Fix]
  The commit let btusb reset at second time it resume, i.e. btusb_open(). The btusb stops working because the reset happens *after* btusb_open(). The reset should be done at hub port initialization, before btusb_probe().

  Revert the bad commit and use the reset-resume quirk in USB core
  stack.

  [Test]
  Cherry-picked the commit into Artful/OEM kernel and the issue is fixed.

  [Regression Potential]
  Low. This is limited to QCA Rome, also verified by the original quirk author.
