Alex Zhuravlev 3910184d9e Use zap_count instead of cached z_size for unlink ... As a performance optimization Lustre does not strictly update the SA_ZPL_SIZE when adding/removing from non-directory entries. This results in entries which cannot be removed through the ZPL layer even though the ZAP is empty and safe to remove. Resolve this issue by checking the zap_count() directly instead on relying on the cached SA_ZPL_SIZE. Micro-benchmarks show no significant performance impact due to the additional overhead of using zap_count().
