spice: do not stop spice if VM is paused

Browse Source 
spice_server_vm_start/stop() was added to help migration state (commit
f5bb039c6d97ef3e664094eab3c9a4dc1824ed73).

However, a paused VM could keep running the spice server. This will
allow a Spice client to keep sending commands to a spice chardev. This
allows to stop/cont a VM from a Spice monitor port. Character
devices (vdagent/usb/smartcard/..) should not read from Spice when the
VM is paused.
