ext4: fix wrong return err in ext4_load_and_init_journal()
The return value is wrong in ext4_load_and_init_journal(). The local variable 'err' need to be initialized before goto out. The original code in __ext4_fill_super() is fine because it has two return values 'ret' and 'err' and 'ret' is initialized as -EINVAL. After we factor out ext4_load_and_init_journal(), this code is broken. So fix it by directly returning -EINVAL in the error handler path.
