[PATCH 03/10] btrfs: Remove unused variable

[Nikolay Borisov <nborisov@suse.com>]

Src was initially part of 31ff1cd25d37 ("Btrfs: Copy into the log tree in
big batches"), however 16e7549f045d ("Btrfs: incompatible format change to remove hole extents") changed parameters passed to copy_items which made the src 
variable redundant.
