nouveau: Fix crash when pci_ram_rom() returns a size of 0
From b15b244d6e6e20964bd4b85306722cb60c3c0809 Mon Sep 17 00:00:00 2001
From: Benjamin Herrenschmidt <benh@kernel.crashing.org>

Subject:
Under some circumstances, pci_map_rom() can return a valid mapping
but a size of 0 (if it cannot find an image in the header).
This causes nouveau to try to kmalloc() a 0 sized pointer and
dereference it, which crashes.
