ext4: fix ext4_show_options for file systems w/o journal

Browse Source 
commit 50b29d8f03 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: 1e381f60da ("ext4: do not allow journal_opts for fs w/o journal")
