navigate march: Plug memory leaks

Browse source 
When the player aborts the command at the movement prompt, or declines
to abandon a sector, unit_move() returns without freeing the list.
Found with valgrind.  Broken in commit 24000b4 and commit 7c1b166,
both v4.3.33.

Free the list on these returns, too.
