clocksource: Initialize cs->wd_list

Browse source

commit 5b9e886a4a upstream.

A number of places relies on list_empty(&cs->wd_list), however the
list_head does not get initialized. Do so upon registration, such that
thereafter it is possible to rely on list_empty() correctly reflecting
the list membership status.
