pointless optimisation. we know that when a user requests an operation that would write, it will probably result in a change. therefore, this change is the real optimisation. to avoid writing the same half of a file twice, when using cmd_copy, we check (in writeGbe) whether gbe part 0 and 1 are the same; if they are, then we only loop once. this is important, because otherwise we would call swap() twice. this means that the optimisations in cmd_copy and cmd_swap must be removed. the point of this and other changes is to improve memory safety in nvmutil, so frivolous use of pointers has to go.
