sleep: rework what we do if a suspend fails.

Browse Source 
First of all, let's fix logging: let's simply log the same message as we
do on success, so that there's always the same pair of these messages
around, regardless if the suspend was successful or not. To distuingish
a successful suspend from a failed one, check the ERRNO= field of the
structured message.

In most ways a failed suspend cycle is not distuingishable from a
successful one that took no time, hence let's treat it this way, and
always pair the success message with a failure message.

This also changes a more important concept: the post-suspend callouts
are now called also called on failure, following the same logic: let's
always run them in pairs: for every pre callout a post callout has to
follow.
