Akihiko Odaki b1d5667afa KVM: arm64: Populate fault info for watchpoint 
commit 811154e234 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.

Fixes: 8fb2046180 ("KVM: arm64: Move early handlers to per-EC handlers")
