pull: plug minor memory leak after using is_descendant_of()

cmd_pull() builds a commit_list to pass a single potential ancestor to
is_descendant_of().  The latter leaves the list intact.  Release the
allocated memory after the call.

Leaking in cmd_*() isn't a big deal, but sets a bad example for other
users of is_descendant_of().
