We return EINVAL when the clockid is not valid. That can mean two
things. Either the SYS-V style hard coded positive clockid is out of
range, or the dynamic negative clockid does not refer to a valid
instance of a clock object.

Dynamic clocks might also return ENODEV in case a hot-plugable device
(like USB) has disappeared after its character device was opened.

Thanks,
Richard
