Subject: [PATCH] ecryptfs: Fix inodes not being evicted until unmount

On asynchronous base filesystems like NFS, eCryptFS leaves inodes for
deleted files in the cache until unmounting. Change call in
ecryptfs_do_unlink() from set_nlink() to drop_nlink() in order to reliably
evict inodes from the cache even on top of NFS.
