Qu Wenruo 13a62fd997 btrfs: scrub: remove scrub_bio structure
Since scrub path has been fully moved to scrub_stripe based facilities,
no more scrub_bio would be submitted.
Thus we can remove it completely, this involves:

- SCRUB_SECTORS_PER_BIO macro
- SCRUB_BIOS_PER_SCTX macro
- SCRUB_MAX_PAGES macro
- BTRFS_MAX_MIRRORS macro
- scrub_bio structure
- scrub_ctx::bios member
- scrub_ctx::curr member
- scrub_ctx::bios_in_flight member
- scrub_ctx::workers_pending member
- scrub_ctx::list_lock member
- scrub_ctx::list_wait member

- function scrub_bio_end_io_worker()
- function scrub_pending_bio_inc()
- function scrub_pending_bio_dec()
- function scrub_throttle()
- function scrub_submit()

- function scrub_find_csum()
- function drop_csum_range()

- Some unnecessary flush and scrub pauses
