udevadm monitor report with hidp_get_raw_report patch applied

With patch 92151 applied, the 5 second penalty is avoided. As this log shows,
things are much better with the input/event devices being removed in their
proper order.

There are still some bits out of order though - this is because of the race
condition in the code between the hci code and the hidp_session code.

However, with this patch the events are in order enough for userspace (i.e.
Xorg evdev driver) to be happy - the keyboard/mouse is disconnected from the
Xserver, making room for a new connection later.
