sequencer: remove unreachable exit condition in pick_commits()

This was introduced by 56dc3ab ("sequencer (rebase -i): implement the
'edit' command", 2017-01-02), and was pointless from the get-go: all
early exits from the loop above are returns, so todo_list->current ==
todo_list->nr is an invariant after the loop.
