x86/kvm: fix a missing-prototypes "vmread_error"

Browse Source 
The commit 842f4be958 ("KVM: VMX: Add a trampoline to fix VMREAD error
handling") removed the declaration of vmread_error() causes a W=1 build
failure with KVM_WERROR=y. Fix it by adding it back.

arch/x86/kvm/vmx/vmx.c:359:17: error: no previous prototype for 'vmread_error' [-Werror=missing-prototypes]
 asmlinkage void vmread_error(unsigned long field, bool fault)
                 ^~~~~~~~~~~~
