btrfs: make btrfs_truncate_block() to be subpage compatible
btrfs_truncate_block() itself is already mostly subpage compatible, the
only missing part is the page dirtying code.
Currently if we have a sector that needs to be truncated, we set the
sector aligned range delalloc, then set the full page dirty.
The problem is, current subpage code requires subpage dirty bit to be
set, or __extent_writepage_io() won't submit bio, thus leads to ordered
extent never to finish.
So this patch will make btrfs_truncate_block() to call
btrfs_page_set_dirty() helper to replace set_page_dirty() to fix the
problem.
