[PATCH 2/2] vringh: Include spinlock.h

[Eugenio Pérez]

Commit f53d9910d009 ("vringh: add 'iotlb_lock' to synchronize iotlb
accesses") introduces this dependency, but does not include spinlock.h.
While kernel seems to compile as usual, tools/virtio cannot do the
same.

Fixes: f53d9910d009 ("vringh: add 'iotlb_lock' to synchronize iotlb accesses")
