NFS: Fix a potential NULL dereference in nfs_get_client()
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.
Fixes: 31434f496abb ("nfs: check hostname in nfs_get_client")
