Implement vmap/vunmap so we can export dmabufs to
other drivers, such as video4linux.
Tested with a virtio-gpu / vivid (virtual capture driver)
pipeline, where the vivid driver imports the dmabufs exported
by virtio-gpu.
Note that dma_buf_vmap() does its own vmap counting, so
it's not needed to take care of it in the driver.
