NFS: Fix a race in __nfs_list_for_each_server()
commit 9c07b75b80eeff714420fb6a4c880b284e529d0f upstream.
The struct nfs_server gets put on the cl_superblocks list before
the server->super field has been initialised, in which case the
call to nfs_sb_active() will Oops. Add a check to ensure that
we skip such a list entry.
Fixes: 3c9e502b59fb ("NFS: Add a helper nfs_client_for_each_server()")
