dma: kmsan: export kmsan_handle_dma() for modules
commit 19fac3c93991502a22c5132824c40b6a2e64b136 upstream.
kmsan_handle_dma() is used by virtio_ring() which can be built as a
module. kmsan_handle_dma() needs to be exported otherwise building the
virtio_ring fails.
Export kmsan_handle_dma for modules.
