Kernels w/genfb but w/o VGA_POST build fails w/unused-but-set warning

["John D. Baker" <jdbaker%mylinuxisp.com@localhost>]

Kernel configs which include "genfb" but which do not include "options
VGA_POST" fail to build due to "curmode" at line 792 of
"src/sys/arch/x86/pci/pci_machdep.c" being set but never used.

The following patch resolves the issue:
