Give the user a chance to re-enter their cryptodisk passphrase after a typo,
rather than immediately failing (and likely dumping them into a GRUB shell).
By default, we allow 3 tries before giving up. A value in the
cryptodisk_passphrase_tries environment variable will override this default.
The user can give up early by entering an empty passphrase, just as they
could before this patch.
