btrfs: scrub: remove scrub_ctx::csum_list member

Since the rework of scrub introduced by commit 2af2aaf98205 ("btrfs:
scrub: introduce structure for new BTRFS_STRIPE_LEN based interface")
and later commits, scrub no longer keeps its data checksum inside sctx.

Instead we have scrub_stripe::csums for the checksum of the stripe.
Thus we can remove the unused scrub_ctx::csum_list member.
