Agathe Porte d9d6a47b24 ufs: ufs_sb_private_info: remove unused s_{2, 3}apb fields ...

BugLink: https://bugs.launchpad.net/bugs/2087853

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.
