cleanup: fix over-eager Coverity warnings
Technically get_dive() could return a nullptr. The existing code made sure the
argument passed to get_dive() was one that always would result in a valid dive
pointer being returned. The new code is only slightly less efficient but allows
a static code analysis to easily see that we don't derefence NULL pointers here.
On some level this change is unnecessary. But it's also not wrong.
Fixes CID 354762
