[cip-dev][isar-cip-core][PATCH 2/3] initramfs-crypt-hook: suppress stderr log from cryptsetup

From: Quirin Gylstorff <[email protected]>

LuksDump prints additional information to stderr on Debian Sid,
this information is not necessary for the grep command. Suppress
the messages to avoid cluttering the boot log.
