Berthold Stoeger 32d042e73e profile: mute a Coverity warning 
CID 376698 was a false positive, but understandable.

It is very hard for Coverity to realize that current_dive
cannot be null if editedDive is not-null.

By replacing current_dive by originalDive, the alert
should go away, since the latter is not checked for null.
