rust_binder: never return 0 from next_debug_id
Retry if fetch_add returns 0 in next_debug_id() so that valid debug IDs
start at 1 and 0 is never assigned, even if NEXT_DEBUG_ID wraps around.
This allows 0 to be used as a sentinel for an absent or uninitialized
debug_id (such as in TransactionInfo::to_node_debug_id and in
transaction log entries).
