In the (alleged) fix to ~~WT-15173~~, an error was introduced. When reallocing zero elements, realloc returns NULL, and it is not an error. Dying at that point is not the right thing to do.

A clean and general fix is to modify drealloc to allow a NULL return (without error) if zero elements is allocated. Same with dmalloc, dcalloc.
