[PATCH] ktest: Restore stty setting at first in dodie

["Masami Hiramatsu (Google)" <mhiramat@kernel.org>]

From: Masami Hiramatsu (Google) <mhiramat@kernel.org>

The do_send_email() will call die before restoring stty if sendmail
setting is not correct or sendmail is not installed. It is safer to
restore it in the beginning of dodie().
