Fix --kernel and --initrd options w.r.t. sparse mem_t implementation

For some reason, the old accessors for the non-sparse version were left
dangling.  These methods are used by the --kernel and --initrd options,
and so those options were just broken.

This also fixes a memory leak and refactors the implementation a bit.
