arch/x86/kvm/emulate.c: In function 'x86_emulate_insn':
arch/x86/kvm/emulate.c:5686:22: error: cast between incompatible
function types from 'int (*)(struct x86_emulate_ctxt *)' to 'void
(*)(struct fastop *)' [-Werror=cast-function-type]
rc = fastop(ctxt, (fastop_t)ctxt->execute);
Fix it by using an unnamed union of a (*execute) function pointer and a
(*fastop) function pointer.
Fixes: 3009afc6e3 ("KVM: x86: Use a typedef for fastop functions")
