Instead of passing lazy_itable_init=1 and lazy_journal_init=1 to mkfs.ext4, pass assume_storage_prezeroed=1 which is stronger and allows the filesystem to skip inode table zeroing completely instead of simply doing it lazily. The support for this flag is checked by trying to format a fake temporary image with mkfs.ext4 and checking its STDERR. Closes: #4948 Signed-off-by: Niraj Yadav <niryadav@redhat.com>
