btrfs: drop unused parameter refs from visit_node_for_delete()

Browse Source 
The parameter duplicates what can be effectively obtained from
wc->refs[level - 1] and this is what's actually used inside. Added in
commit 2b73c7e761 ("btrfs: unify logic to decide if we need to walk
down into a node during snapshot delete").
