hw/hyperv: fix NULL dereference with pure-kvm SynIC
When started in compat configuration of SynIC, e.g.
qemu-system-x86_64 -machine pc-i440fx-2.10,accel=kvm \
-cpu host,-vmx,hv-relaxed,hv_spinlocks=0x1fff,hv-vpindex,hv-synic
or explicitly
qemu-system-x86_64 -enable-kvm -cpu host,hv-synic,x-hv-synic-kvm-only=on
QEMU crashes in hyperv_synic_reset() trying to access the non-present
qobject for SynIC.
Add the missing check for NULL.
