[PATCH] fix "info cpus" halted state display

[Gleb Natapov <gleb@redhat.com>]

When in-kernel irqchip is used env->halted is never used for anything
except "info cpus" command. Halted state is synced in
kvm_arch_save_mpstate() and showed by do_info_cpus() but otherwise never
looked at. Zeroing it here breaks "info cpus" since before
do_info_cpus() outputs env->halted in io thread it is zeroed here when
vcpu thread reenters kernel.
