Fix dive computer interleaving so it works again

Merging two different dives by interleaving dive computer data got
broken by the multi-dive-computer code in commit b6c9301e58 ("Move
more dive computer filled data to the divecomputer structure") which
added a lot more entries to the dive computer data structure, and then
copied the resulting structure incorrectly.

Make sure we don't copy the events and samples allocations when we copy
all the other fields of the divecomputer.
