performance/stat-prefetch: Add support code to implement lookup-behind.
- change sp_lookup and sp_lookup_cbk to support sending lookups when needed. lookups might need to be sent in fops like open, chmod, chown etc which operate on a path, since the actual lookup sent to stat-prefetch by its parent xlators is not propagated down the xlator tree if the path is cached.
