vfio/migration: Fix incorrect initialization value for parameters in VFIOMigration
The structure VFIOMigration of a VFIODevice is allocated and initialized
in vfio_migration_init(). "device_state" and "vm_running" are initialized
to 0, indicating that VFIO device is_STOP and VM is not-running. The
initialization value is incorrect. According to the agreement, default
state of VFIO device is _RUNNING. And if a VFIO device is hot-plugged
while the VM is running, "vm_running" should be 1. This patch fixes it.
Fixes: 02a7e71b1e5b ("vfio: Add VM state change handler to know state of VM")
