Kees Cook 2326aceebc KVM: arm64: vgic-its: Remove VLA usage
In the quest to remove all stack VLA usage from the kernel[1], this
switches to using a maximum size and adds sanity checks. Additionally
cleans up some of the int-vs-u32 usage and adds additional bounds checking.
As it currently stands, this will always be 8 bytes until the ABI changes.
