NFS: Fix an Oops in nfs_d_automount()
[ Upstream commit 35e3b6ae84935d0d7ff76cbdaa83411b0ad5e471 ]
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")
