ext4: ignore mount options supported by ext2/3 (but have since been removed)
Users who tried to use the ext4 file system driver is being used for
the ext2 or ext3 file systems (via the CONFIG_EXT4_USE_FOR_EXT23
option) could have failed mounts if their /etc/fstab contains options
recognized by ext2 or ext3 but which have since been removed in ext4.
So teach ext4 to recognize them and give a warning that the mount
option was removed.
