pangliyuan 77e5266e3d ubifs: skip dumping tnc tree when zroot is null ...

[ Upstream commit bdb0ca39e0acccf6771db49c3f94ed787d05f2d7 ]

Clearing slab cache will free all znode in memory and make
c->zroot.znode = NULL, then dumping tnc tree will access
c->zroot.znode which cause null pointer dereference.
