mkfs still sets the sb_features bitmask for all the supported v4
features it uses by default on v5 superblocks. There are some
feature bits in the v4 mask that are optional for v5 superblocks,
too (e.g. case insensitivity, sunit/swidth alignment), so we won't
ever stop setting the XFS_SB_VERSION_DIRV2BIT on v5 superblocks...
