[PATCH] nsf4 oops fixes

Here are some oops I found in error paths in the mounting pathes while
debugging something else...  I sent it out a while ago, but it didn't seem
to get any traction....

The nfs_fill_super() fix is obvious and in nfs4_fill_super(), the
server->client ptr needs to be set before the cl_idmap check, since
rpc_shutdown_client() needs it when the check fails.
