KVM: arm64: vgic-its: Add a data length check in vgic_its_save_*
commit 7fe28d7e68f92cc3d0668b8f2fbdf5c303ac3022 upstream.
In all the vgic_its_save_*() functinos, they do not check whether
the data length is 8 bytes before calling vgic_write_guest_lock.
This patch adds the check. To prevent the kernel from being blown up
when the fault occurs, KVM_BUG_ON() is used. And the other BUG_ON()s
are replaced together.
