xfs: fix zero byte checking in the superblock scrubber
The logic to check that the region past the end of the superblock is all
zeroes is wrong -- we don't want to check only the bytes past the end of
the maximally sized ondisk superblock structure as currently defined in
xfs_format.h; we want to check the bytes beyond the end of the ondisk as
defined by the feature bits.
Port the superblock size logic from xfs_repair and then put it to use in
xfs_scrub.
