kernel: KVM: arm64: vgic-its: Drop the translation cache reference only for the erased entry

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM for ARM64, specifically within the vgic-its component. This vulnerability occurs when multiple concurrent operations incorrectly drop the translation cache's reference to an entry more than once during cache invalidation. Thi...
