btrfs: scrub: refactor scrub_find_csum()
Function scrub_find_csum() is to locate the csum for bytenr @logical
from sctx->csum_list.
However it lacks a lot of comments to explain things like how the
csum_list is organized and why we need to drop csum range which is
before us.
Refactor the function by:
- Add more comments explaining the behavior
- Add comment explaining why we need to drop the csum range
- Put the csum copy in the main loop
This is mostly for the incoming patches to make scrub_find_csum() able
to find multiple checksums.
