hw-breakpoints, x86: Fix modular KVM build
This build error: arch/x86/kvm/x86.c:3655: error: implicit declaration of function 'hw_breakpoint_restore' Happens because in the CONFIG_KVM=m case there's no 'CONFIG_KVM' define in the kernel - it's CONFIG_KVM_MODULE in that case. Make the prototype available unconditionally.
