score: Critical fix for timer server

Browse Source 
Under certain conditions it is possible that a call to
_Watchdog_Adjust_to_chain() happens with a unit parameter value of zero
(for example sptests/spintrcritical17).  Remove superfluous checks that
prevent an adjust to a chain of a watchdog chain which first element has
a delta zero value.
