NFS: Fix a potential NULL dereference in nfs_get_client()

[ Upstream commit 09226e8303beeec10f2ff844d2e46d1371dc58e0 ]

None of the callers are expecting NULL returns from nfs_get_client() so
this code will lead to an Oops.  It's better to return an error
pointer.  I expect that this is dead code so hopefully no one is
affected.
