Delete any instances of include module.h that were not strictly required. In the case of ext2, the declaration of MODULE_LICENSE etc. were in inode.c but the module_init/exit were in super.c, so relocate the MODULE_LICENCE/AUTHOR block to super.c which makes it consistent with ext3 and ext4 at the same time.
