There is only one caller of this functions which calls it under
strictly defined conditions. Error checking and return value
can be removed.

BTW it looks like the whole point of this request list is to implement
the throttle ioctl? Looks like a strange ioctl with a fixed 20ms criteria,
could it be re-implemented somehow without having to have this list?
Does it have to be per-client or could it wait for any requests on any
engine emitted 20ms ago?
