commit 6aa42966dea9a1fc02a714211ea489c3278bf8d4

bluetooth: Take a runtime pm reference on hid connections
Bluetooth runtime PM interacts badly with input devices - the connection
will be dropped if the device becomes idle, resulting in noticable lag when
the user interacts with the input device again. Bump the pm runtime count
when the device is associated and release it when it's disassociated in
order to avoid this.

bluetooth: Remove some unnecessary error messages
The main reason for these urbs to error out on submission is that runtime
pm has kicked in, which is unnecessary noise. Let's just drop them.

bluetooth: Enable USB autosuspend by default on btusb
We've done this for a while in Fedora without any obvious problems other
than some interaction with input devices. Those should be fixed now, so
let's try this in mainline.
