This fixes a warning and bug in Linus tree,

  CC      arch/x86/kernel/apic/x2apic_uv_x.o
/home/airlied/git/linux-2.6/arch/x86/kernel/apic/x2apic_uv_x.c: In
function ‘uv_system_init’:
/home/airlied/git/linux-2.6/arch/x86/kernel/apic/x2apic_uv_x.c:882:2:
warning: passing argument 1 of ‘pci_register_set_vga_state’ from
incompatible pointer type [enabled by default]
/home/airlied/git/linux-2.6/include/linux/pci.h:1094:13: note:
expected ‘arch_set_vga_state_t’ but argument is of type ‘int
(*)(struct pci_dev *, bool,  unsigned int,  bool)’
