Move the vcpu_has_feature() function to asm/kvm_host.h in preparation for
replacing test_bit() feature checks.

struct kvm_vcpu is defined in linux/kvm_host.h, which includes
asm/kvm_host.h; the function has been transformed into a macro to avoid
compiler errors about struct kvm_vcpu being undefined.
