KVM: x86/xen: Fix cleanup logic in emulation of Xen schedop poll hypercalls
commit 5a53249d149f48b558368c5338b9921b76a12f8c upstream.
kvm_xen_schedop_poll does a kmalloc_array() when a VM polls the host
for more than one event channel potr (nr_ports > 1).
After the kmalloc_array(), the error paths need to go through the
"out" label, but the call to kvm_read_guest_virt() does not.
Fixes: 92c58965e965 ("KVM: x86/xen: Use kvm_read_guest_virt() instead of open-coding it badly")
