x86/cpu: Provide a declaration for itlb_multihit_kvm_mitigation
Sparse complains rightfully about the missing declaration which has been
placed sloppily into the usage site:
bugs.c:2223:6: sparse: warning: symbol 'itlb_multihit_kvm_mitigation' was not declared. Should it be static?
Add it to <asm/spec-ctrl.h> where it belongs and remove the one in the KVM code.
