btrfs: split page locking out of __process_pages_contig

Browse source

There is a lot of complexity in __process_pages_contig to deal with the
PAGE_LOCK case that can return an error unlike all the other actions.

Open code the page iteration for page locking in lock_delalloc_pages and
remove all the now unused code from __process_pages_contig.
