[PATCH 2/7] rebase -i: don't error out if $state_dir already exists

[Ramkumar Ramachandra <artagnon@gmail.com>]

Practically speaking, the only reason why a `mkdir $state_dir` would
fail is because $state_dir already exists.  There is no problem in
this case, and we can proceed as usual.  So, change the `mkdir` call
to `mkdir -p`, and strip the `|| die`.
