media: videobuf2-dma-sg: fix vmap callback

Browse source

commit 608ca5a60e upstream.

For dmabuf import users to be able to use the vaddr from another
videobuf2-dma-sg source, the exporter needs to set a proper vaddr on
vb2_dma_sg_dmabuf_ops_vmap callback. This patch adds vmap on map if
buf->vaddr was not set.
