Benjamin Herrenschmidt ea71f98d68 nouveau: Fix crash when pci_ram_rom() returns a size of 0

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.
