btrfs: defrag: use btrfs_mod_outstanding_extents in cluster_pages_for_defrag

Since commit 8b62f87bad9c ("Btrfs: rework outstanding_extents"),
manual operations of outstanding_extent in btrfs_inode are replaced by
btrfs_mod_outstanding_extents().
The one in cluster_pages_for_defrag seems to be lost, so replace it
of btrfs_mod_outstanding_extents().
