These two fields are populated and stored as a "frequently used value" in ufs_fill_super, but are not used afterwards in the driver. Moreover, one of the shifts triggers UBSAN: shift-out-of-bounds when apbshift is 12 because 12 * 3 = 36 and 1 << 36 does not fit in the 32 bit integer used to store the value.
