[PATCH kvm-kmod] fix undefined kvm_vfio_ops

[Jonas Pfoh]

vfio.c is being pulled in from the submodule, but it is not being compiled/linked by the build environment, causing a "Unknown symbol in module" error when loading the resulting module.

Adding vfio.o to the kvm-objs variable in x86/Kbuild fixes this issue

Format was almost perfect format - just your mailer mangled whitespaces.
Make sure to either use git send-email then or to switch of line-wrapper
etc. in the mail client when sending patches - to whichever project.

Unfortunately it broke the build for 3.11 and older kernels. I merged a
variant to next that passed build tests here.

Thanks,
Jan
