Btrfs: cleanup arguments to extent_clear_unlock_delalloc
This patch removes the io_tree argument for extent_clear_unlock_delalloc since we always use &BTRFS_I(inode)->io_tree, and it separates out the extent tree operations from the page operations. This way we just pass in the extent bits we want to clear and then pass in the operations we want done to the pages. This is because I'm going to fix what extent bits we clear in some cases and rather than add a bunch of new flags we'll just use the actual extent bits we want to clear.
