hw/i386/vmport: Assert vmport initialized before registering commands
vmport_register() is also called from other modules such as vmmouse.
Therefore, these modules rely that vmport is realized before those call
sites. If this is violated, vmport_register() will NULL-deref.
To make such issues easier to debug, assert in vmport_register() that
vmport is already realized.
