Subject: [PATCH] clockevents: warn once when program_event() is called with
 negative expiry

The hrtimer problem with large relative timeouts resulting in a
negative expiry time went unnoticed as there is no check in the
clockevents_program_event() code. Put a check there with a WARN_ONCE
to avoid such problems in the future.
