kvm: Remove the unused macro KVM_MMU_READ_{,UN}LOCK()
No code is using KVM_MMU_READ_LOCK() or KVM_MMU_READ_UNLOCK(). They
used to be in virt/kvm/pfncache.c:
KVM_MMU_READ_LOCK(kvm);
retry = mmu_notifier_retry_hva(kvm, mmu_seq, uhva);
KVM_MMU_READ_UNLOCK(kvm);
However, since 58cd407ca4c6 ("KVM: Fix multiple races in gfn=>pfn cache
refresh", 2022-05-25) the code is only relying on the MMU notifier's
invalidation count and sequence number.
