Move trace_vfio_migration_set_state() to the top of the function, add
recover_state to it, and add a new trace event to
vfio_migration_set_device_state().
This improves tracing of device state changes as state changes are now
also logged when vfio_migration_set_state() fails (covering recover
state and device reset transitions) and in no-op state transitions to
the same state.
