NFS: Fix an Oops in nfs_d_automount()
When mounting from a NFSv4 referral, path->dentry can end up being a negative dentry, so derive the struct nfs_server from the dentry itself instead. Fixes: 2b0143b5c986 ("VFS: normal filesystems (and lustre): d_inode() annotations") Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>
