- fix unbalanced invocation of pci_enable_device();

- leaks plugged in cirrusfb_zorro_setup();

- move framebuffer_release() into cirrusfb_{pci/zorro}_unmap() to balance
  cirrusfb_{pci/zorro}_setup();

- make cirrusfb_{pci/zorro}_setup() return adequate error codes when
  something fails;

- cirrusfb_zorro_unmap: iounmap() now take as argument values previously
  returned by ioremap().
