Revert "Bluetooth: btusb: fix QCA Rome suspend/resume"

This reverts commit c79644699745f8bcf73f044414c96220f245fe55.

This commit causes a regression on some QCA ROME chips. The USB device
reset happens in btusb_open(), hence firmware loading gets interrupted.

Furthermore, this commit stops working after commit
("f04c9e6a65f25f728421db9c18819203a214ebeb Bluetooth: btusb: driver to
enable the usb-wakeup feature"). Reset-resume quirk only gets enabled in
btusb_suspend() when it's not a wakeup source.

If we really want to reset the USB device, we need to do it before
btusb_open(). Let's handle it in drivers/usb/core/quirks.c.
