btrfs: raid56: switch scrub path to use a single function

Browse source

This switch involves the following changes:

- Make finish_parity_scrub() only to submit the write bios
  It will no longer call rbio_orig_end_io(), and now it will
  return error.

- Add a new helper, recover_scrub_rbio(), to handle recovery
  It's just doing extra scrub related checks, and then call
  recover_sectors().

- Rename raid56_parity_scrub_stripe() to scrub_rbio()
- Rename scrub_parity_work() to scrub_rbio_work_locked()
  To follow the existing naming scheme.

- Delete unused functions
  Including:
  * finish_rmw()
  * raid_write_end_io()
  * raid56_bio_end_io()
  * __raid_recover_end_io()
