btrfs: scrub: move logical/physical/dev/mirror_num from scrub_sector to scrub_block
Currently we store the following members in scrub_sector:
- logical
- physical
- physical_for_dev_replace
- dev
- mirror_num
However the current scrub code has ensured that scrub_blocks never cross
stripe boundary.
This is caused by the entry functions (scrub_simple_mirror,
scrub_simple_stripe), thus every scrub_block will not cross stripe
boundary.
Thus this makes it possible to move those members into scrub_block other
than putting them into scrub_sector.
This should save quite some memory, as a scrub_block can be as large as 64
sectors, even for metadata it's 16 sectors byte default.
