Re: [PATCH v2 net] net: fddi: fix a possible null-ptr-deref

bp->SharedMemAddr is set to NULL while bp->SharedMemSize lesser-or-equal 0,
then memset will trigger null-ptr-deref.

fix it by replacing pci_alloc_consistent with dma_zalloc_coherent.

v1->v2: move from pci_dma* to dma_* as Christoph suggested

Applied.
