From: Debabrata Banerjee <dbanerje@xxxxxxxxxx>
commit 50b29d8f033a7c88c5bc011abc2068b1691ab755 upstream.
Instead of removing EXT4_MOUNT_JOURNAL_CHECKSUM from s_def_mount_opt as
I assume was intended, all other options were blown away leading to
_ext4_show_options() output being incorrect.
Fixes: 1e381f60dad9 ("ext4: do not allow journal_opts for fs w/o journal")
