KVM: arm64: Populate fault info for watchpoint
commit 811154e234db72f0a11557a84ba9640f8b3bc823 upstream.
When handling ESR_ELx_EC_WATCHPT_LOW, far_el2 member of struct
kvm_vcpu_fault_info will be copied to far member of struct
kvm_debug_exit_arch and exposed to the userspace. The userspace will
see stale values from older faults if the fault info does not get
populated.
