ext4: don't call ext4_should_journal_data() on the journal inode
commit 6a7fd522a7c94cdef0a3b08acf8e6702056e635c upstream.
If ext4_fill_super() fails early, it's possible for ext4_evict_inode()
to call ext4_should_journal_data() before superblock options and flags
are fully set up. In that case, the iput() on the journal inode can
end up causing a BUG().
Work around this problem by reordering the tests so we only call
ext4_should_journal_data() after we know it's not the journal inode.
Fixes: 2d859db3e4 ("ext4: fix data corruption in inodes with journalled data")
Fixes: 2b405bfa84 ("ext4: fix data=journal fast mount/umount hang")
