btrfs: scrub: use dedicated super block verification function to scrub one super block

There is really no need to go through the super complex scrub_sectors()
to just handle super blocks.  Introduce a dedicated function to handle
super block scrubbing.

This new function will introduce a behavior change, instead of using the
complex but concurrent scrub_bio system, here we just go submit-and-wait.

There is really not much sense to care the performance of super block
scrubbing. It only has 3 super blocks at most, and they are all
scattered around the devices already.
