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.
