    kvm: Remove unused variable from mmu_shrink_scan()
    
    "LIST_HEAD(invalid_list)" is no longer used in mmu_shrink_scan()
    since RedHat has backported mainline commit
    ebdb292dac79 ("KVM: x86/mmu: Batch zap MMU pages when shrinking the slab").
    
    Let us remove it.
    
    Found while working on https://jira.sw.ru/browse/PSBM-131982.
    
    mFixes: ms commit ebdb292dac79 ("KVM: x86/mmu: Batch zap MMU pages when
    shrinking the slab")
