[PATCH] virtio-iommu: Fix coverity issue in virtio_iommu_handle_command()

[Eric Auger]

Coverity points out (CID 1430180) that the new case is missing
break or a /* fallthrough */ comment. Break is the right thing to
do as in that case, tail is not used.

Fixes 1733eebb9e ("virtio-iommu: Implement RESV_MEM probe request")
