xfs_scrub: vectorize kernel calls [v30.9 22/28]

Create a vectorized version of the metadata scrub and repair ioctl, and
adapt xfs_scrub to use that.  This is an experiment to measure overhead
and to try refactoring xfs_scrub.

This has been running on the djcloud for months with no problems.  Enjoy!
