chenrun1 8f9857bf8c fs_lock:Check the nwaiter when deleting a bucket ...

Summary:
  Fixed the problem of releasing the bucket prematurely in multi-threaded flock scenarios.

A thread setlk
B thread setlk_wait
A thread releases lock but fails to determine if nwaiter causes the bucket to be released prematurely
post B thread causes crash due to heap use after free
