[PATCH 4/6] btrfs: Pass 0 for bio_offset to btrfs_wq_submit_bio

[Nikolay Borisov <nborisov@suse.com>]

Buffered writeback always calls btrfs_csum_one_bio with the last 2
arguments being 0 irrespective of what the bio_offset has been passed
to btrfs_submit_bio_start. Make this apparent by explicitly passing 0
for bio_offset when calling btrfs_wq_submit_bio from
btrfs_submit_bio_hook. This will allow for further simplifications down
the line. No functional changes.
