[PATCH 2/2] Revert "expand-on-first-boot: Expand crypto_LUKS partition"

["'Jan Kiszka' via isar-users" <isar-users@googlegroups.com>]

From: Jan Kiszka <jan.kiszka@siemens.com>

This reverts commit c44c088cd224e44a401410c860bd625f28950ac3.

Same argument as for reverting 8b30a4f86cb3: This does not work when the
initramfs properly hides the encryption secret after using it.
