  Fix non-working QCA Rome Bluetooth after S3

Status in linux package in Ubuntu:

Bug description:
  Sometimes QCA Rome Bluetooth USB host doesn't work after S3:
  [ 165.110742] Bluetooth: hci0: using NVM file: qca/nvm_usb_00000302.bin
  [ 168.432065] Bluetooth: hci0: Failed to send body at 4 of 1953 (-110)

  This is due to USB core enables LPM two times after S3.

  Only enable LPM once.

  The Bluetooth USB works all the time after applying the fix.

  [Regression Potential]
  Low. Enabling a hardware feature twice in a row isn't right, I'd be surprise 
if any hardware relies on this driver behavior.
