According to include/uapi/linux/kvm_para.h architectures should define
kvm_para_available, so add an implementation to asm-generic/kvm_para.h
which just returns false.

What is this fixing? The only user of kvm_para_available() that can
benefit from this is in sound/pci/intel8x0.c, but I do not see follow up
patch to use it there.

It was an unintentional config with mips + kvm + intel8x0 that hit it
(I think I accidentally based my mips config off an x86_64 config).
Kind of equivalent to a randconfig build failure I suppose.
