This patch fixes the issue by:
  1) Use kzalloc to initialize to a well known state.
  2) Put 'struct pci_sysdata' at the start of 'pcifront_sd'. That

(This, btw, is the second time we got bitten by pcifront_sd bit not being pci_sysdata. dc4fdaf0e48 was a workaround for a similar problem and we should have fixed it then).
