In the case where setup_git_directory_gently fails, avoid the last
chdir("..") by moving it after the ceil_offset check.

Johannes originally asked me to squash this, then asked me to keep the
patch minimal. I'm including it here in case anyone else thinks it should
go in. It should be harmless because getcwd is not called in the loop,
and any nonlocal exit from the loop is either a "die" or does a chdir
to cwd, which is an absolute path.
