btrfs: fix incorrect comparison for delayed refs
When I reworked delayed ref comparison in cf4f04325b2b ("btrfs: move
->parent and ->ref_root into btrfs_delayed_ref_node"), I made a mistake
and returned -1 for the case where ref1->ref_root was > than
ref2->ref_root. This is a subtle bug that can result in improper
delayed ref running order, which can result in transaction aborts.
Fixes: cf4f04325b2b ("btrfs: move ->parent and ->ref_root into btrfs_delayed_ref_node")
