Bluetooth: btusb: Revert Fix the autosuspend enable and disable
drivers/usb/core/hub.c: usb_new_device() contains the following:
/* By default, forbid autosuspend for all devices. It will be
* allowed for hubs during binding.
*/
usb_disable_autosuspend(udev);
So for anything which is not a hub, such as btusb devices, autosuspend is
disabled by default and we must call usb_enable_autosuspend(udev) to
enable it.
This means that the "Fix the autosuspend enable and disable" commit,
which drops the usb_enable_autosuspend() call when the enable_autosuspend
module option is true, is completely wrong, revert it.
This reverts commit 7bd9fb058d77213130e4b3e594115c028b708e7e.
