[PATCH][next] btrfs: remove redundant variable pages_processed

[Colin Ian King <colin.i.king@gmail.com>]

Variable pages_processed is being accumulated but it is not being
used after this. An earlier commit 6d6a31e7fc99 ("btrfs: split page
locking out of __process_pages_contig") removed the check on
pages_processed, so this variable is now redundant and can be removed.
