nfs: make sillyrename an async operation
A synchronous rename can be interrupted by a SIGKILL. If that happens during a sillyrename operation, it's possible for the rename call to be sent to the server, but the task exits before processing the reply. If this happens, the sillyrenamed file won't get cleaned up during nfs_dentry_iput and the server is left with a dangling .nfs* file hanging around. Fix this problem by turning sillyrename into an asynchronous operation and have the task doing the sillyrename just wait on the reply. If the task is killed before the sillyrename completes, it'll still proceed to completion.
